I'm not sure that's a keyboard combination since you're also getting
a hanging screen. Is this always happening in the same program or
various programs? Does the hanging screen respond to any input at
all? Does the hanging screen clear up on its own or do you have to do
something to handle it? Does Ctrl + Z bring the text back once the
hanging screen is restored to normal?

This might be a hardware issue. I'm not sure which brand of mouse you
use, but our Logitech mice typically start doing that when they wear
out. We always keep spare mice around because they always do that and
it comes on rather suddenly, eventually doing it more frequently
followed by continuing to get worse by either clicking too many times
or refusing to click at all. Replacing the mouse always takes care of
it for us, and the mouse behaves just as badly if put onto another
computer, so it's a sure-fire diagnosis. Do you have another mouse you
can test or another computer you can plug that mouse into to see if
the issue goes away when the mouse is replaced or follows the mouse
when it goes elsewhere?
