You can throw your mouse away with this keyboard remapping| vim gang

[cutbypham]

• Video demo: https://youtu.be/pKtIrQsbKnQ

• Hold Tab

• h j k l moving cursor left down up right (vim) || hold tab + space + hjkl speed is slow down
• w button left, e button middle, r button right
• ; scroll down, p scroll up, i scroll left, o scroll right

I use qwerty layout

• With this basic ideas you can use input remapper or the software you can think can do with action
• Input remapper config: https://github.com/thuanowa/dotfiles/blob/3e8b63c4f9020ed05b0c159ab901d2e82c421b55/input-remapper/presets/SEMICO%20%20%20USB%20Gaming%20Keyboard%20/thuan_fly_key.json

with version >= 1.5.1, kinda broken

[cutbypham]

fix with mouseless: https://github.com/jbensmann/mouseless
mouseless config: jbensmann/mouseless#25 (comment)

[trapexit]

Can this be done by using a second input device as a Fn key of sorts? I have a Thinkpad with a physical middle mouse button and would like to replicate the layering system I have with my TEX Shinobi (where the middle mouse button is also a Fn key).

[trapexit]

Perhaps I'm misunderstanding what you're describing but what I'm looking for is not to control a mouse with the keyboard but kinda the reverse. On the TEX Shinobi keyboard you can use the middle mouse button as a Fn key and I use that to issue key presses that would require moving away from the home row such as mapping h, j, k, l to arrow keys when middle mouse button is held down. ie: MiddleMouseButton + h = left

[cutbypham]

I can remap a held down switch to layer hjkl to arrow keys while a single key press keeps the a function.

https://program.tex.com.tw/shinobi/#keymap

[cutbypham]

the example I map s when held down switch to layer

layers:
  - name: initial
    bindings:
      s: tap-hold s ; toggle-layer uwu ; 300

  - name: uwu
    passThrough: false
    bindings:
      s: layer initial
      i: layer uwu
      j: pagedown
      k: pageup
      h: left
      l: right

[trapexit]

Are you saying it can't use the mouse button to switch layers? I don't seem to be able to capture any mouse button with input-remapper.

[cutbypham]

yes.
