What are your favorite keyboard shortcuts on Mac OS X?
On newer keyboards, invoke Exposé to
- fn+F3: show all windows (in the current Space)
- fn+⌘+F3: show the desktop
- fn+ctrl+F3: show the "current application" windows
- fn+⌥+F3: show the Exposé preference pane
While being in Exposé,
- cycle through windows with the arrow keys, using return to bring them into focus.
- use ⇥ and ⇧+ ⇥ to cycle through windows by applications (as highlighted in the Dock)
⌘+z [undo] is my favorite & the one I tell the people I support to remember if they only learn one shortcut. In Finder it undoes the last operation you just performed from inadvertently beginning to rename a file or folder; or undoing an unintentional drag and drop of a file or folder into the wrong folder or undoing a move to trash operation. In applications many have multiple levels of undo which lets you step backward undoing previous edits or draws. Extremely useful in extricating yourself from sticky situations or just after having made a simple mistake.
