How to disable all global hotkeys in KDE Plasma?

Question

I'm using a KDE+i3 setup on my machine and therefore I want to disable all the global hotkeys provided by KDE, since I've binded the keys properly in my i3-config.
Upon exploring qdbus API, I've found out the command works per Plasma session:

qdbus org.kde.kglobalaccel /kglobalaccel blockGlobalShortcuts true

Issues

The issue is how to begin with its automation. The following are the issues:

• Global keys start working again after Sleep, Lock etc. which restart Plasma.
• I've used

  exec --no-startup-id qdbus org.kde.kglobalaccel /kglobalaccel \
  blockGlobalShortcuts true
  

  for now but only works till Plasma doesn't restart.

How should I proceed with implementing this?

Answer 1

I've found a way to disable all the global shortcuts of KDE. Here's what I did:

• The hotkeys are saved in ~/.config/kglobalshortcutsrc in the form of foo=bar assignments.
• Using sed, replace the hotkeys.
• Restart kglobalaccel to observe the changes.

Here's the script:

#!/bin/sh

hotkeysRC="$XDG_CONFIG_HOME/kglobalshortcutsrc"

# Remove application launching shortcuts.
sed -i 's/_launch=[^,]*/_launch=none/g' $hotkeysRC

# Remove other global shortcuts.
sed -i 's/^\([^_].*\)=[^,]*/\1=none/g' $hotkeysRC

# Reload hotkeys.
kquitapp5 kglobalaccel && sleep 2s && kglobalaccel5 &

Now I can finally move all of my key bindings to i3 config!

Answer 2

I slightly modified the script by Utkarsh since it didn't work for my installation (probably syntax in kglobalshortcutsrc has changed):

#!/bin/sh

fl="$HOME/.config/kglobalshortcutsrc"

sed -i 's/=.*,.*,/=none,none,/g' $fl
sed -i 's/Walk Through Windows=.*/Walk Through Windows=Alt+Tab,Alt+Tab,Walk Through Windows/' $fl # return alt+tab

# Reload hotkeys.
kquitapp5 kglobalaccel && sleep 2s && kglobalaccel5 &
