“Clicking the X” in spectrwm

Question

I'm happily using spectrwm and looking for a way to "click the X", to close a window and kill the process.

MOD+W just make the window disappear, the process keeps running.

Edit: That's intended behavior because MOD+W is for "iconify".

How can I stop programs that don't offer the infamous File->Exit or some similar way of closing them without kill?

Answer 1

"Mod + X" by default. Meaning if you haven't configured your keyboard shortcuts to something else.
