Keyd Setup for ASUS ROG FALCHION Keyboard

This guide installs and configures keyd to remap keys on the ASUS ROG FALCHION keyboard.

1. Install keyd
   sudo add-apt-repository ppa:keyd-team/ppa
   sudo apt update
   sudo apt install keyd
   sudo systemctl enable --now keyd

2. Find Your Keyboard’s Vendor:Product:ID
   The keyd executable installed by the package may be named keyd.rvaiya instead of keyd.
   Run with full path:
   sudo /usr/bin/keyd.rvaiya monitor
   Press any key and look for output like (for example):
   ASUSTeK ROG FALCHION 0b05:193e:5a05be1d rightcontrol down
   The 0b05:193e:5a05be1d is your keyboard ID.

(Optionally, create a symlink for convenience:
sudo ln -s /usr/bin/keyd.rvaiya /usr/local/bin/keyd
Then you can run sudo keyd monitor as usual.)

3. Configure Key Remapping
   Edit the keyd configuration:
   sudo nano /etc/keyd/default.conf
   Add the following:

[ids]  
0b05:193e:5a05be1d  

[main]  
rightcontrol = left  
rightshift = up  
left = down

[control+alt]  
space = macro(C-S-u 2004 enter)  # optional

Save and exit (Ctrl + X, Y, Enter).

4. Apply Changes
   sudo systemctl restart keyd

5. Test the Remapping
   Run with full path or symlink:
   sudo /usr/bin/keyd.rvaiya monitor
   (or sudo keyd monitor if symlink created)
   Press Right Ctrl, Right Shift, Left → Should map as Left, Up, Down.

6. Verify Final Mapping
   sudo /usr/bin/keyd.rvaiya list-keys
   (or sudo keyd list-keys if symlink created)
   If needed, force apply:
   sudo /usr/bin/keyd.rvaiya bind rightcontrol=left

Done! Reboot and test again.
