Alt-Tab in Windows, how do you do that on a Mac?

In Windows, Alt+Tab switches between all open windows of all applications; there is not a direct equivalent on the Mac. However, Command+Tab (aka Apple+Tab) switches between applications (as the previous poster wrote), and Command+~ (Apple+~) switches between windows/documents within an application.

Hope this helps!

Same thing works on a Mac, but its Command-Tab. Its one of the keys to the left of the space bar. Works exactly the same as in windows.

Apple (command) tab is similar but instead of switching between windows, it switches between appliccations.

Yeah, Command + Tab no worky in many games that are in full screen
