Is there a Ctrl + Tab equivalent on Mac OS X?

I want to cycle trough the windows of the currently active application on Mac OS X. Some applications respond to Ctrl + Tab but they all seem to do something else. I want to switch between the Entourage mainscreen and the message I am writing for instance. Is there a such a keyword shortcut?

Solution 1:

Command + ` (the ~ key) works with many programs.

Solution 2:

Depends on the application but most of them support:

• Command + Shift + [

• Command + Shift + ]

for switching between tabs.

Solution 3:

There is a piece of shareware called Witch that emulates Windows alt+tab. It shows all windows in all applications, sorted by application. It costs €9.95.

Solution 4:

It depends on your settings. Default settings depend on your locale.

See System Preferences -> Keyboard and Mouse -> Keyboard Shortcuts to see what the keys are on your system for e.g. "Move focus to next window in active application"
