问题
Let us say that I have two Xcode projects open on a Mac and I am going back and forth between them. Is there any hot key that can do this (rather then constantly using the mouse). Something analogous to COMMAND + TAB to flip through applications.
回答1:
⌘ + ` (above tab on US/en keyboards) will go through open windows in the current app. use shift to reverse the direction.
