Hi folks! When I try Ctrl+Alt+Click on an existing thickness node, it doesn't get deleted, duplicated in the same place (Alt key is like being completely ignored here). According to this Reddit post, it's an unexpected behavior. Is it an issue in my keyboard or in Inkscape?

I tried to find settings to change keyboard shortcut (if it's incorrectly set on my system to Ctrl+Alt+Click) but failed. Then I thought that maybe my keyboard is sending the wrong signal to the Inkscape (I'm not good at this stuff, but please correct me if I'm wrong about how all this works). And if it's the case maybe can you recommend me some Linux tool (if I'm thinking in the right direction of course) to let me understand which combination of keys to press to let them be interpreted as Ctrl+Alt+Click?
