karabiner-input-switch

What

A Karabiner config to remap input language switch hotkey to Alt+Shift.

Why

shift-alt.json

The default hotkey combination (Ctrl+Space) is nice, however it conflicts with suggestion hotkey at VS Code. To fix this, I decided to remap language switching to Alt+Shift, but macOS doesn't support that out of the box, and, long story short, I ended up with this setup.

I haven't been able to come up with a better hotkey for suggestion prompt, and I'm switching platforms (to Linux and Windows) a lot. This solution works better than any alternatives I've tried.

fn.json

Because Apple can't simply make the Globe key switch inputs. It shows some slow UI, using which is a terrible experience.

How

1. Install Karabiner.

2. Copy shift-alt.json and fn.json to the ~/.config/karabiner/assets/complex_modifications/.

   cp *.json ~/.config/karabiner/assets/complex_modifications/

3. Start Karabiner and enable the config.

4. Go to the system input settings of the macOS and rebind the input switch to whatever pressing the Alt+Shift or the Globe/Fn key emit.
