Hi Marc,

Ctrl + A is a standard keyboard shortcut for the action \"Select All\" and is probably something you don\'t want to modify.

However, here are two apps that allow you to modify the shortcuts if necessary:

And if you\'re looking to create keyboard shortcuts for specific apps, here\'s how you can achieve this:

Hope this helped.
