If you use a computer much at all, you quickly realize that time spent reaching for your mouse is time wasted. It sounds trivial, but somehow, the effort to move your hand to the mouse, move it to figure out where the cursor is, and then do whatever it is you need to do has a magical ability to slow me down and break my concentration. Any time I can keep my hands on the keyboard rather than the mouse or the trackpad, it’s a victory.
So, it was with great excitement that I happened upon CheatSheet today. Install it, and hold down the command key, and voila:
A list of keyboard shortcuts for the current application.
It’s not perfect, and it doesn’t catch all shortcuts in every app – but it’s useful enough to install.
