Note that you can also use cmd+tab and then while continuing to hold the chord use the pointer to select an application switch to.
You also do things like (for example) start a drag, ⌘+tab to show running apps, then drop on an app icon without using the dock.
I always only use cmd-tab to open the switcher, then I use arrow keys to pick an application, up/down arrows to view an application’s windows (arrow keys and enter to select a specific one)
You can also hit Q to quit an application from the switcher and probably more things I’m currently forgetting.
As repetitive as these top-tips threads can be, we need one every now and again. Someone's guaranteed to learn something from them, and I'm grateful it was my turn today.
The way I learned these shortcuts was reading macOS's help back in 2007, but the quality of documentation bundled with macOS has gone downhill quite a bit.
