Ever wonder what the command and option keys are on your keyboard. Maybe you know command+c is copy and command+v is paste. Well the command key⌘, and your option/alt key⌥ can do so much more.
There are so many shortcuts that it can be a little overwhelming. You can try adopting one or two at a time and slowly build up your use of these shortcuts.
A few of my favorites beyond copy and paste:
|Force Quit: Choose an app to force quit. Or press Command- Shift-Option-Esc and hold for 3 seconds to force just the front app to quit.
|Spotlight: Show or hide the Spotlight search field. To perform a Spotlight search from a Finder window, press Command–Option– Space bar. If you use multiple input sources to type in different languages, these shortcuts change input sources instead of showing Spotlight.
|Find: Open a Find window, or find items in a document.
