Scenario: I have open Firefox A and Firefox B and putty A and putty B.
I'd like to be able to attach a custom global keyboard shortcut for focusing either of these windows. For example, set Ctrl+Alt+F2 to focus putty B (other shortcuts are suitable, too).
I can set the title of the windows if must, or I can launch the processes in a specific order. Or anything that works even for one session (PIDs, etc.).
On Mac this is said to be possible with Witch but how to do it with Windows?
