Since updating to Studio 2021 I have been having an issue with the control+alt+down arrow shortcut. I translate mainly financial documents so being able to insert numbers is pretty useful to me. The problem is that if I access a segment, go to another segment and then return to the former segment the shortcut no longer works. E.g. I ctrl+enter segment 111 , note a spelling error in the just completed segment, fix it, ctrl+enter again - in segment 112 ctrl+alt+down no longer works.

This also happens if I accidentally click into another segment. E.g. I'm working on segment 222, accidentally click on segment 224, when I click back into segment 222, ctrl+alt+down doesn't work.
