Keyboard Maestro and BetterTouchTool have been my favorite Mac utilities for many years.<p>One tiny example: I use hidutil + Keyboard Maestro to map my Caps Lock key to CMD+Tab. I found that constantly hitting CMD+Tab throughout the day caused me some wrist strain.<p>So instead, I now map my Caps Lock to Keypad 0 using hidutil. And then I use Keyboard Maestro to invoke CMD+Tab everytime Keypad 0 occurs. So now, CMD+Tab is just a single keystroke. It's a small win, but it's something that I do many many times per day.<p>A second example: I use 1Password, but <i>sometimes</i> some apps or sites DO NOT allow me to paste my password. Ugh. So I use a Keyboard Maestro macro to type out my copied password. Now that I think of it, I hope they're not stealing all my passwords! ;-)
