TIL: cmd + tab has a bunch of extras
On macOS cmd + tab brings up the application switcher. “Yes,” you say, “I have used a computer before.”

But there are a bunch of extras!
- if you keep the cmd key depressed, you can use
tab,shift + tab,~, the left/right arrow keys, or even the mouse to select the application to activate. - press
qwhen an application is selected to quit the program - press
hwhen an application is selected to hide it - press up/down when an application is selected to show all its windows in an Exposé view
- if you are dragging a file, you can drop it onto an icon in the switcher (I can’t say I’ve ever used this one. I typically drag-and-drop to the Dock but maybe there are cases where the application switcher is more convenient)
