Top 10 Hot Corner Actions You Should Be Using TodayHot corners are a small but powerful feature found on many operating systems and third‑party utilities. By assigning an action to a screen corner, you can trigger common tasks instantly with a flick of the mouse — saving time, reducing friction, and keeping your hands on the trackpad or mouse. Below are ten highly useful hot corner actions, how to set them up (macOS, Windows, and common third‑party tools), practical use cases, and tips for avoiding accidental triggers.
1. Show Desktop / Reveal Desktop
Why it’s useful
- Quickly access files or folders on the desktop without minimizing windows.
- Great for dragging items to/from the desktop or glancing at files.
How to set it up
- macOS: System Settings → Desktop & Dock → Hot Corners → choose “Desktop”.
- Windows (no built-in hot corners): Use tools like PowerToys (FancyZones + shortcuts) or third‑party utilities (e.g., Hot Corners for Windows).
- Linux: Many desktop environments (GNOME/KDE) support hot corner extensions or settings.
Practical tips
- Combine with keyboard shortcuts (Cmd/Ctrl + click) for precision.
- If you use multiple monitors, set the hot corner on the primary display.
2. Mission Control / Exposé (Show All Windows)
Why it’s useful
- Instantly view all open windows to find a specific app or document.
- Speeds up window switching, especially with many open apps.
How to set it up
- macOS: System Settings → Desktop & Dock → Hot Corners → choose “Mission Control”.
- Windows: Use Task View shortcut (Win + Tab) or assign a corner via third‑party utilities.
- Linux: Configure the workspace switcher or an extension for an exposé‑like view.
Practical tips
- Use with keyboard shortcuts (e.g., Alt+Tab for cycling, Mission Control for overview).
- Pair with trackpad gestures if you prefer swipes over corners.
3. Put Display to Sleep / Lock Screen
Why it’s useful
- Quickly secure your machine or save power without navigating menus.
- Useful when stepping away for a short time.
How to set it up
- macOS: Hot Corners → choose “Lock Screen” or “Put Display to Sleep”.
- Windows: Use a shortcut to lock (Win + L) and assign it to a hot corner via third‑party apps.
- Linux: Assign screen‑lock command to a corner via system settings or custom scripts.
Practical tips
- On shared workstations, locking with a hot corner is faster than menus.
- Choose a corner you won’t hit accidentally.
4. Launch a Specific App or Script
Why it’s useful
- Open a frequently used app or run an automation with one corner swipe.
- Ideal for launching music, a note app, or a quick automation script.
How to set it up
- macOS: Use Automator/Shortcuts to create an action, then assign via Hot Corners (or use third‑party tools like BetterTouchTool).
- Windows: Use AutoHotkey or third‑party hot corner utilities to run .exe or scripts.
- Linux: Hook a corner to a shell script or application command.
Practical tips
- Example: map a corner to open a timer app or a new email compose window.
- Keep scripts lightweight so they run instantly.
5. Show Notification Center / Action Center
Why it’s useful
- Glance at notifications and system toggles without hunting through menus.
- Useful for checking messages, calendar alerts, or quick settings.
How to set it up
- macOS: Assign “Notification Center” in Hot Corners.
- Windows: Map a corner to open Action Center via third‑party tools or touches that trigger Win + A.
- Linux: Use a desktop environment’s notification panel mapping.
Practical tips
- Good to place on a corner you use rarely for other actions to avoid accidental clears.
- Combine with Do Not Disturb schedules for focused work.
6. Start/Stop Screen Recording or Screenshot
Why it’s useful
- Capture quick recordings or screenshots for tutorials, bug reports, or notes.
- Saves time compared with opening full-screen capture apps.
How to set it up
- macOS: Use Shortcuts or Automator to create a record/screenshot action and assign to hot corner via BetterTouchTool or Shortcuts (macOS Ventura+).
- Windows: Use Xbox Game Bar shortcuts or AutoHotkey scripts bound to hot corner tools.
- Linux: Tie a corner to a scrot/gnome-screenshot or SimpleScreenRecorder command.
Practical tips
- Configure a short delay if you need to arrange windows before capture.
- Keep captures saved to a predefined folder for easy retrieval.
7. Toggle Do Not Disturb / Focus Mode
Why it’s useful
- Silence interruptions instantly for deep work sessions.
- Easier than digging through settings when you need quick focus.
How to set it up
- macOS: Create a Shortcuts action that toggles Focus and map it via a tool that supports Hot Corners.
- Windows: Use Focus Assist settings and a script to toggle it from a corner via third‑party utilities.
- Linux: Use desktop notifications control scripts routed to a corner.
Practical tips
- Use alongside a visible indicator (menu bar or status icon) so you know when focus mode is active.
- Consider configuring automatic schedules for recurring focus times.
8. Switch to Desktop/Another Workspace
Why it’s useful
- Move between virtual desktops quickly to separate tasks (work, personal, media).
- Keeps context switching fast and intentional.
How to set it up
- macOS: Assign corners for “Desktop” or use Mission Control to manage spaces.
- Windows: Use Virtual Desktops (Win + Ctrl + Left/Right) and third‑party tools to bind corners to specific desktop switches.
- Linux: Map corners to switch workspaces in GNOME/KDE settings.
Practical tips
- Label or color‑code desktops mentally (or with widgets) to remember their purpose.
- Avoid assigning adjacent corners to similar workspace actions to reduce misfires.
9. Open Today’s Calendar / Create New Event
Why it’s useful
- Instantly check your schedule or add events without opening a full calendar app.
- Helpful when you need to confirm meeting times or add quick reminders.
How to set it up
- macOS: Create a Shortcut that opens Calendar to Today or creates a new event; assign to Hot Corner via Shortcuts or BetterTouchTool.
- Windows: Use a script to open your calendar app or web calendar; bind via third‑party utilities.
- Linux: Trigger a calendar app or notification via a corner‑bound command.
Practical tips
- Pre-fill common event templates (e.g., 15‑minute quick meeting) in your shortcut to speed entry.
- Combine with a voice shortcut for hands‑free event creation.
10. Run a Custom Automation (Workflows, Shortcuts, AppleScript, AutoHotkey)
Why it’s useful
- Automate repetitive tasks like opening a project workspace, starting a timer, or sending a status message.
- Turns hot corners into powerful triggers for complex sequences.
How to set it up
- macOS: Shortcuts, Automator, or AppleScript → assign to Hot Corner via BetterTouchTool or Shortcuts.
- Windows: AutoHotkey, PowerShell scripts, or Power Automate Desktop → bind with a hot corner app.
- Linux: Shell scripts, Python scripts, or automation tools, bound to a corner.
Practical tips
- Keep one corner reserved for an emergency “panic” workflow (e.g., hide sensitive windows, mute audio, lock screen).
- Test automations and include small delays where needed to avoid race conditions.
Best practices to avoid accidental triggers
- Use a “dead zone” by placing most useful actions in corners you don’t often push to.
- Enable a short delay or require a corner hold (0.3–0.5s) where supported.
- Reserve the most destructive actions (close all windows, log out) for combinations (corner + modifier) or avoid assigning them entirely.
- Document your chosen corners so teammates who use your machine understand the setup.
Hot corners are a small ergonomic tweak with outsized payoffs: they reduce friction, speed routine tasks, and make your mouse gestures more purposeful. Start by mapping one or two low‑risk actions (Show Desktop, Lock Screen), then expand to automations and app launches as you get comfortable.
