Hi, I'm trying to remap Super+C to Ctrl+C using xkb, but I don't want to remap Super to Ctrl because I'm still using Super for other shortcuts. I have achieved this X using interpret F13 { RedirectKey(keys=c,modifiers=Control,clearmodifiers=Super) } and set symbols c to [c, C, F13]

I have tried set symbols c to [c, C, XF86Copy] on Mod4 xkb type but XF86Copy doesn't work with some applications because I still have modifier Super set when pressing Super+C

It would be great to have a way to clear modifier without using RedirectKey, or should I do something else.
