Most of us know the basics. Command-Tab to switch. Command-C to copy. Command-V to paste. Command-Q to quit an app. After that the keyboard shortcuts we know are probably few and far between, even if we use an app daily. What Mac users need is a cheat sheet for keyboard shortcuts for each app. That’s where the free app CheatSheet is aptly named.
Whatever Mac app you’re using at the time usually has a few keyboard shortcuts. Sure, you could explore each menu selection in the Mac’s Menubar, then write down the ones you need (or, worse, try to remember them).
Or, add CheatSheet to your Mac. Press and hold the Command key and CheatSheet pops up all the keyboard shortcuts for that app.
If you want to know more about how CheatSheet works, well, there isn’t any more. Press the Command key and hold until CheatSheet pops up. What you get is a list of all the keyboard shortcuts for the frontmost app on your Mac.
Caveats? Yes, a few.
I’ve run into a couple of issues with Adobe apps (Surprise! Adobe does things their own way), and there needs to be an easier or faster way to make the keyboard shortcut popup disappear, but it’s hard to complain about the price. CheatSheet requires Mac OS X 10.7 or newer.
