20 Slack Hidden Features That Save You Hours Every Week
You use Slack every single day. You send messages, check channels, maybe drop an emoji or two. But here is the thing: you are probably using about 10% of what Slack is truly capable of.
Much like finding the perfect software egg, there are features buried inside Slack right now that can save you hours every week. Features that cut through notification chaos, help you find old messages in seconds, handle repetitive tasks without writing a single line of code, and even turn Slack into a smart AI assistant that works for you.
Most people have never heard of them.
This article is going to change that.
Who Really Needs This?
If any of these sound familiar, keep reading:
- You scroll through Slack for minutes just to find a message from last week
- Your sidebar is a wall of channels and you don’t know where to start
- Notifications interrupt you every 10 minutes while you’re trying to focus
- You copy and paste the same update into five different channels every week
- You leave meetings only to forget who said what
Whether you work at a startup, a large company, or you’re freelancing with remote clients, these features will make your workday noticeably smoother.
What People Are Really Looking For
When people search “Slack hidden features,” they want one thing: real tricks that work, explained in simple, everyday language. Not a list of settings menus. Not corporate jargon. Just useful stuff they can try right now.
That is what this article delivers.
1. The Quick Switcher (The Feature That Will Save You the Most Time)
Press Ctrl + K on Windows or Cmd + K on Mac.
That’s it. That one shortcut will change how you use Slack forever.
A search bar pops up. You type a channel name, a person’s name, or even just a keyword. Slack takes you there instantly. No scrolling through a 40-channel sidebar. No clicking around.
Most people have never pressed those two keys. Once you do, you’ll wonder how you ever managed without it.
Pro tip: You can also press Ctrl + T (or Cmd + T on Mac) to do the same thing. Try both and see which one fits better.
2. Reminder Messages (Your Personal To-Do List Inside Slack)
Ever read a message and thought, “I’ll deal with this later,” then completely forgot about it?
Slack has a fix for that.
Hover over any message and click the three-dot menu. You’ll see an option that says “Remind me about this.” Pick a time, in 20 minutes, in an hour, tomorrow morning, and Slack will send you a private reminder at that time.
You can also type /remind directly into the message box. For example:
/remind me to send the project update at 3pm
Slack will ping you at 3 pm. No switching apps. No sticky notes.
3. Slack Canvas (A Shared Document That Lives Inside Your Channel)
Most people think of Slack as a chat tool. But there is a solid document feature sitting right inside it called Canvas.
Think of Canvas like a shared Google Doc, except it lives directly inside a Slack channel or DM. You can write notes, add checklists, embed links, and even attach workflows. Every team member in that channel can see it, edit it, and come back to it later.
Where to find it: Look for the document icon at the top of any channel. Click it and your Canvas opens.
Teams use it for things like:
- Meeting notes that stay with the channel forever
- Onboarding documents for new teammates
- Project briefs and task lists
- Weekly updates that everyone can check at any time
The best part? You never have to say “I’ll send that document over” again. It’s already there.
4. Keyword Notifications (Get Pinged Only for What Matters)
Slack notifies you about everything by default. Every message in every channel. It becomes noise fast.
Here is a much smarter setup: keyword notifications.
Go to Preferences > Notifications > My Keywords. Add words that matter to you, your client’s name, your project name, words like “urgent” or “budget” or “launch.”
Now Slack will only notify you when those words appear in any channel. Even channels you have muted.
You stay quiet and focused. But the second something that matters to you comes up, you’ll know.
5. Message Formatting That Most People Skip
Plain text works. But formatted messages are easier to read, especially in busy channels.
Here are the formatting shortcuts you should know:
| What You Want | What You Type |
|---|---|
| Bold | *your text* |
| Italic | _your text_ |
| ~~Strikethrough~~ | ~your text~ |
Code text | `your text` |
| Bullet list | Start a line with – |
| Numbered list | Start a line with 1. |
| Block quote | Start a line with > |
When you’re writing an important announcement or a long update, this makes a real difference. People read the whole message instead of skimming past it.
6. Slash Commands (Hidden Shortcuts Right Inside the Message Box)
Slack has a shortcut system sitting right inside the message box. You just type a forward slash, and a whole menu of commands appears.
Here are the most useful ones:
- /away: Set your status to Away right away
- /dnd 2 hours: Turn on Do Not Disturb for 2 hours
- /remind: Set a reminder for yourself or someone else
- /invite @name: Add someone to a channel without leaving the conversation
- /collapse: Collapse all images and files in a channel to reduce clutter
- /expand: Bring them all back
- /shortcuts: See every command available to you
Try typing just / in the message box right now. You’ll be surprised at what comes up.
7. Do Not Disturb Mode With a Schedule
Most people know Slack has a Do Not Disturb mode. Not many know you can set it on a schedule so it runs by itself.
Go to Preferences > Notifications > Notification Schedule. Set your working hours. Slack will stop sending notifications outside those hours every single day, on its own.
You close your laptop at 6 pm. No more Slack pings until you decide to start again. No more “just checking one thing” that turns into 45 minutes of scrolling.
Your personal time stays yours.
8. Search Operators (Find Any Message Ever Sent)
Slack’s basic search is fine. But if you know the special search operators, you can find almost anything in seconds.
Try these in the Slack search bar:
from:@sarah: Shows only messages sent by Sarahin:#marketing: Shows only messages in the marketing channelhas:link: Shows messages that contain a linkhas:star: Shows your starred messagesbefore:2025-01-01: Shows messages before a specific dateafter:2024-06-01: Shows messages after a specific date
Combine them for even more power: from:@sarah in:#design has:link will show you every link Sarah ever posted in the design channel.
That important decision from eight months ago? You’ll find it in 10 seconds.
9. Workflow Builder (Put Repetitive Tasks on Autopilot Without Coding)
Every Monday morning, does someone post a standup reminder? Does someone always send the same update to five channels?
Workflow Builder can handle all of that on its own.
It’s a no-code tool inside Slack. You tell it: “Every Monday at 9 am, post this message in #team-updates.” Or: “When someone joins #new-hires, send them a welcome message with these links.”
You set it up once. Slack takes care of it from there.
Where to find it: Click on your workspace name in the top-left corner, then select Tools > Workflow Builder. You can also read through Slack’s official Workflow Builder page if you want to see what types of workflows are possible before you start building.
Teams use it for daily standups, IT request routing, approval flows, and new employee onboarding. If you’re doing the same thing in Slack more than twice a week, there’s probably a workflow that can handle it for you. And if you want to connect outside tools like Google Calendar or Trello to your workflows, the Slack App Directory is the place to browse what’s available.
10. Huddles for Quick Conversations
Sometimes a 5-minute voice call is worth more than 20 messages back and forth.
While you might rely on Zoom Hidden Features for massive company-wide meetings, Slack Huddles let you start a quick, informal audio call with anyone on your team. No scheduling. No invite link. No meeting room. Just click the headphone icon next to any DM or channel and you’re in.
The part most people miss? You can also share your screen and switch on video during a Huddle. Most people only know about the audio side.
Next time you’re stuck in a long text thread trying to explain something complicated, just start a Huddle. You’ll sort it out in a fraction of the time.
11. Save Messages With Bookmarks
Not every message needs a reminder. Sometimes you just want to save something so you can find it easily later.
Hover over any message and click the bookmark icon. The message is saved.
To see all your saved messages, press Ctrl + Shift + S (or Cmd + Shift + S on Mac). Every bookmarked message shows up in one clean list.
It’s a solid way to hold onto resources, decisions, or anything you know you’ll want to come back to.
12. Custom Channel Sections (Organize Your Sidebar the Way You Want)
Is your sidebar just one long, overwhelming list of channels? You can fix that in a few minutes.
Right-click anywhere in your sidebar and select “Create a section.” Name it whatever you want: “Clients,” “Projects,” “Important,” “Low Priority.” Then drag your channels into these sections.
Now instead of scrolling through 50 channels, you have a sidebar organized the way your brain works.
You can collapse sections you don’t need right now and open the ones you’re actively using. It takes five minutes to set up and feels like a completely different app every time you open Slack.
13. Thread Summaries With Slack AI
If you’re on a paid Slack plan, this one is worth knowing about.
When a thread goes long, 30, 40, 50 replies, you don’t have to read all of it. Click the “Summarize” option at the top of any thread, and Slack AI will give you a short, clear summary of what was discussed and what was decided.
It pulls from the actual conversation. You get the key points in about 15 seconds instead of 10 minutes.
This is especially helpful when you’ve been out of the office and come back to a massive thread. Don’t read 60 messages. Just read the summary.
14. Channel Recaps (Catch Up Without Reading Everything)
Slack AI can also give you a daily recap of any channel.
Click into a channel you haven’t read in a while. Look for the “Catch up” option at the top. Slack will pull together everything that happened since you last visited: the main topics, the decisions, the follow-up items.
It’s like having someone read through the channel for you and hand you the notes.
15. Edit Your Last Message Instantly
You sent a message. You immediately spot the typo.
Don’t send a follow-up saying “I meant to say…” Just press the Up Arrow key on your keyboard while your cursor is in the message box.
Your last message opens for editing right away. Fix it. Press Enter. Done.
Two seconds. Clean conversation.
16. Message Scheduling
You figured out the answer to a question at 11 pm. But you don’t want to ping your colleague at 11 pm.
Slack lets you set a message to send at a later time.
Write your message. Then instead of pressing Enter, click the small arrow next to the Send button. Select “Schedule message.” Pick a date and time. Slack will send it then.
Your colleague gets the message at 9 am. You get to sleep. Everyone is happy.
17. Custom Emoji (Makes Your Workspace Feel Like a Real Team)
Every Slack workspace can have its own custom emoji. Words, inside jokes, your company logo, your coworker’s face, anything goes.
Click your workspace name, go to “Settings & Administration” > “Customize [Workspace Name]”, then click the Emoji tab. Upload any image and give it a name.
Now type :youremojiname: in any message and it appears.
This sounds small. But custom emoji are one of those things that make remote teams feel like a real team. They build shared language and inside humor that creates connection across distance.
18. Mark Messages as Unread
You read a message but you’re not ready to respond yet. You want to come back to it later.
Hold Alt and click the message (or right-click and select “Mark as unread”).
The channel goes back to showing as unread. You won’t lose track of it.
It’s a small trick. But it is incredibly useful when you’re in the middle of something and can’t stop to reply right now.
19. Link Text (Make Your Messages Look Much Cleaner)
Instead of pasting a long ugly URL into a message, you can turn any text into a clickable link like this:
- Type your link text, for example, “Click here for the brief”
- Select it
- Press Ctrl + Shift + U (or Cmd + Shift + U on Mac)
- Paste the URL
Now the message says “Click here for the brief” with a clean link instead of a 200-character URL taking up half the screen.
Cleaner messages. Less visual clutter. Easier for everyone to read.
20. Your Status Tells Your Team Everything
Most people set their Slack status once and forget it. But a well-used status can cut down on interruptions dramatically.
Set a status like “Heads down until 2 pm” when you need quiet time. Or “In meetings all morning.” Or “Slow connection today.”
Your teammates see that before they message you. They know not to expect an instant reply. You don’t have to explain yourself every time.
Go to your profile picture, click “Update your status”, set a message, add an emoji, and choose when it clears on its own.
Twenty seconds of setup. Dozens fewer interruptions every week.
What Most Other Articles on This Topic Miss
Most blog posts about Slack stop at keyboard shortcuts and emoji reactions. Here are three things that almost never get mentioned:
Message expiration in channels
In your channel settings, admins can set how long messages are stored before they are removed. Useful for legal compliance and keeping channels clean over time.
Shared channel sections across teams
On some Slack plans, managers can share their custom sidebar layout with an entire team at once. Everyone gets the same organized sidebar without having to set it up themselves.
User profile summaries with AI
On Business+ and higher plans, you can hover over a person’s name and see an AI-generated summary of what they have been working on lately. Very helpful when you are new to a team and need context fast.
Frequently Asked Questions
Are these Slack features free to use?
Most of them are available on all plans, including the free plan. A few AI-powered features like thread summaries and channel recaps require a paid Slack plan (Pro, Business+, or Enterprise+).
Do I need admin access to use these features?
No. Most of these features, including shortcuts, formatting, reminders, bookmarks, and custom sections, are available to every user. Admin access is only needed for workspace-wide settings.
How do I find Slack shortcuts I might have missed?
Press Ctrl + / on Windows (or Cmd + / on Mac) at any time inside Slack. A full list of every available keyboard shortcut opens right there. Slack also maintains a full shortcuts reference on their help site if you want to browse everything in one place.
Can I use Slack Workflow Builder without any coding experience?
Yes. Workflow Builder is fully no-code. You set up workflows using a visual editor where you choose triggers and ac
tions from menus. No programming knowledge needed.
What is the fastest way to search for an old message in Slack?
Use search operators in the search bar. For example, from:@personname in:#channelname keyword narrows results dramatically. You can usually find any message within 10 to 15 seconds using this method.
Does Slack work well for small teams or is it mainly for large companies?
Slack works well for teams of any size. Even two-person teams use it effectively. The free plan has plenty of room for small teams to get started
Conclusion
Slack is a much more capable tool than most people give it credit for. The difference between someone who uses it only for chat and someone who knows these features goes beyond speed. It is a completely different experience at work.
You spend less time searching. Fewer interruptions break your focus. You stop missing important things. Your messages are clearer. Your team stays more in sync.
Pick two or three features from this list that match your biggest frustrations right now. Start with those. Once they feel natural, come back and try a few more.
No need to change everything at once. Just pick one thing and start today.
