Hotkey to focus specific character

This is very basic but I cannot seem to find it in search or wiki. What are the default keys to swap focus between characters/instances?
I see keys for focus next/previous window but not for specific [window 1, 2, 3, etc..].
If there is no default, could someone point me in the right direction towards setting one up?

This is set on the Slots of your Character Set.



The default depends on whether you ticked the "I have an AltGR key" during the Quick Setup Wizard.
By default they also show up in the Title Bar for the application (which you might need to hover over the taskbar to see).

The normal default is CTRL+ALT+x, where x is the Slot number.

I knew I was missing something blatantly obvious. Thank you very much.
