In a previous Keyboard Kung Fu lesson we saw how easy it is to switch between open applications using Command-Tab. Sometimes though, an app is minimised or closed and can’t be tabbed to. That’s where this handy little manoeuvre comes in.
Command-Tab / Command-Option
Use the ⌘ tab / ⌘ ⌥ key combination to open an application that has been minimised or closed. These apps can be brought up by taking your finger off the tab key, moving it to the ⌥ key, and then removing your thumb from the ⌘ key.
In the image above I have already tried to switch to the Mail app but found that it is closed. So I have then used ⌘ tab to select the Mail app and then taken my middle finger off the tab key and put my index finger onto the ⌥ key. Then when I removed my thumb from the ⌘ key the Mail app popped up into the foreground.
