This question already has an answer here:

I have the mouse gestures such as four finger swipe up shows mission control, or four finger swipe down shows current application's windows.

Occasionally after the computer has been on for a while, the shortcuts just stop working. Is there a way I can fix it without having to restart my entire computer?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • This also addresses keyboard shortcuts that stopped working or that you remapped and didn't "take it" and the accepted answer solves that too – Ciprian Tomoiagă Aug 3 '18 at 7:32

You can restart Mission Control using the following command in Terminal:

killall Dock

This will usually fix the mouse gesture shortcuts.
