Say I have two windows of a browser running, how can I switch between those two windows? like Command + Tab?
⌘ Command + `
will cycle between windows of the current application when using i.a. US keyboard.
- ⌘`: Move focus to next window (in application)
- ⌃F4: Move focus to active or next window (visible windows on the current space)
(On the U.S. locale and keyboard layout.)
Both of these allow ⌘ Command + Tab will switch between all windows in all apps in a last used order (or can be configured to another order)
