You need to set system wide hotkeys (those hotkeys work even when VeraCrypt is minimized) to make use of them. Go to Settings | Hot Keys and you can define some hotkeys for these actions:

Auto mount devices

Close all security token sessions

Dismount all and wipe cache

Dismount all, wipe cache and exit

Mount favorite volumes

Show / hide main VeraCrypt windows

Wipe cache

Once you have set shortcut keys for those actions, they'll work in any application. Note that VeraCrypt Background Task has to be running in order to global actions to work.
