Restricting Command+tab options to only apps that are in the current space on Mac

In Mavericks, ^F4 switches through windows in the current space but you may have to upgrade to Yosemite to map this behavior to ^~.

The problem can still be alleviated like so:

System Preferences > Mission Control > Uncheck "When switching to an application, switch to a Space with open windows for the application"


In Yosemite, this behavior can now be mapped to your desired key combination:
System Preferences > Keyboard > Shortcuts > Keyboard > Move focus to active or next window
