Rebind Alt+Backspace to Ctrl+Backspace with keygrabber

[agzam]

OMG, I'm so stuck. Please, I beg you, someone show me how to properly rebind Alt+Backspace to Ctrl+Backspace with awful.keygrabber.

The problem I have is that Alt is still being recognized as "pressed" in the "on_press" handler, therefore simply emmiting Ctrl+BS (I think) is turning it into Ctl+Alt+BS, and that's obviously not what I want. But if I try to root.fake_input "key_release" "Alt_L" it - the whole thing stops working.

Hmmm, I had to throw some time warping 'magic', it looks like maybe it's working, but I need to watch it, it still might break in some weird way later.

(awful.keygrabber
 {:keybindings
  [(awful.key
    ;; Alt+Backspace works just like on Mac
    {:modifiers [:Mod1] :key :BackSpace
     :on_press (fn []
                 (root.fake_input :key_release :Alt_R)
                 (gears.timer.weak_start_new
                  0.01
                  (fn []
                    (root.fake_input :key_release :BackSpace)
                    (root.fake_input :key_press :Control_L)
                    (root.fake_input :key_press :BackSpace)
                    (root.fake_input :key_release :BackSpace)
                    (root.fake_input :key_release :Control_L)
                    (root.fake_input :key_press :Alt_R))
                  false))})]
  :stop_key :Mod1
  :stop_event "release"
  :export_keybindings true
  :root_keybindings [(awful.key {:modifiers [:Mod1] :key :BackSpace})]})
