If you're on a Mac and not utilizing Keyboard Maestro, I'm probably fake enjoying any of our conversations.
But seriously, you can save literal DAYS of time you spend clicking and pressing keys on the keyboard for things you shouldn't have to repeat. To date, Keyboard Maestro has saved me over 3 MONTHS of time. It actually adds up all of the time it saves you! And it's a one-time, no subscription purchase.
Seriously, If I could only install ONE app on a mac, this would be the one by a long shot.
