Corner and Screen Edge Triggers

Actions in the macOS Mission Control in System Preferences

The corner triggers in BetterTouchTool are similar to the default Mission Control Hot Corners in macOS. When you drag your cursor to a designated corner, you can trigger an assigned action, such as putting your desktop display asleep, or showing all open application windows.

While the macOS provides about a dozen actions for its hot corners, BetterTouchTool provides over a hundred actions, including the ability to trigger keyboard shortcuts and menu items in any application.

My BetterTouchTool Trigger

Though I have hundreds of BTT triggers, my hot corners triggers are ones I have started to use throughout the day. Some of these triggers include the following:

  • A Move Mouse to Bottom Edge of Screen trigger to toggle the Play/Stop button of Google Play.
  • Move Mouse to Top Right Corner for hiding and showing the numerous ScreenFloat shots I take throughout the day for various projects I’m working on like this article
  • A Move Mouse Away From Bottom Right Corner to quick resize the front window in the desktop screen recorder, ScreenFlow. This is an application-specific trigger.

Each of the above corner and edge triggers could easily be assigned to finger gesture triggers, but for a heavy BTT user like myself, I’ve practically run out of my favorite finger gestures. The corner triggers provide a few more ways to trigger actions when my hand is already on my trackpad.

    You might want to set a delay time for the trigger to fire so that it doesn’t fire accidentally move your cursor to the designated corner or edge of the
