The message could only cite the modifiers ("after Ctrl+Shift") because
Windows consumes the KEYDOWN of a combo it routed to another app. Its KEYUP
often still arrives though — when it does, report the exact combo the user
tried: "Ctrl+Shift+T is already used by another app".
Falls back to the modifiers-only wording when the key-up is swallowed too.
Can't misfire: an accepted combo ends the capture on keydown, so a non-modifier
key-up during capture means that key was swallowed.
