linux-deep-hotkeys

This script allows you to use Space-key as a modifier key like Shift or Ctrl and as a usual Space-key at the same time.

This script adds the following bindings:

   Space + j = Left
   Space + l = Right
   Space + i = Up
   Space + k = Down
   Space + u = Backspace
   Space + o = Delete
   Space + h = Home
   Space + ; = End
   Space + n = PageUp
   Space + m = PageDown

   Ctrl+Alt+Win+q = quit script
   Ctrl+Alt+Win+z = pause/unpase bindings

But you can modify it as you like.

Step 1 : install evdev

Evdev is a library for working with input devices.

To install it for Ubuntu:

sudo apt-get install python-dev python3-pip gcc

sudo pip install evdev 

For more details and other distros please see:

Step 2 : get script

wget https://raw.githubusercontent.com/LexRiver/linux-deep-hotkeys/main/linux-deep-hotkeys.py

Step 3 : run script

To modify keyboard codes user must be in group input, so run the script as root.

sudo python3 linux-deep-hotkeys.py

Select your keyboard when asked.

Check if binding is working.

To modify key bindings

Edit the script linux-deep-hotkeys.py line number around 50 keycodes_to_bind

Run the script like so:

sudo python3 linux-deep-hotkeys.py --device /dev/input/event3

Again, to find your keyboard name, run the script without arguments.
