How to track all shortcut keys pressed and the process they interact with?

For a while now and for some reason I find myself in the unpleasant situation of Ctrl-w not working anymore in any program, which means I need the mouse any time I want to close a tab. I tried checking general Debian keyboard shortcuts, input method shortcuts etc. but didn't find any conflict so far. However, it's not like there's zero reaction. When I press Ctrl-w in Firefox for example, the vertical scrollbar on the right gets highlighted until I release the keys. In Kate, the cursor stops blinking for an instant. So the strategy I came up with is somehow finding a log which tells me which program or process is being triggered by any keypress (or just shortcuts would do fine)... I found out all keys pressed can be logged using programs like KeyLogger or logkeys ; but they don't seem to make a link to the action triggered by those keypresses... Is there a way to track any activity triggered by the keys I press in Debian 10 AVL-MXE? Like tail but realtime (or non-realtime) monitoring/logging of anything I'm doing? Or another way to solve my "Ctrl-w not working anymore" problem? Thanks so much for any clue! some system info: Kernel : Linux 5.9.1-rt20avl1 (x86_64) Version : #1 SMP PREEMPT_RT Sat Oct 31 12:21:58 EDT 2020 C Library : GNU C Library / (Debian GLIBC 2.28-10) 2.28 Distribution : Debian GNU/Linux 10 (buster)
