If you use Keyboard Maestro a good tip is to both create a hotkey and a status menu item. Then you can look at the status menu to remember your keystroke.
Yes, if you click through on the above link, you’ll see I’m linking to a footnote. While I set up the “meta key” mentioned in the post a year or so ago,1 it never entered my mind to use the Keyboard Maestro status menu (in the menu bar) as a cheatsheet. This will be especially handy with new macros, before I commit the hotkey to memory.
