This program does 2 things:

• It adds a layer behind a “toggle key” that can be configured based on the active application.

• It creates a pop-up to show what each key will do when the toggle is being held.

You can turn either of these features on/off with options in a config.json file.

This script currently only works on windows. This isn’t ideal but none of this code is “ideal”. It’s quick and dirty because it evolved from a much simpler script.

I think the program could be useful when learning new keyboard layers because it gives you a way to visually search for the keys on a layer. You can customize the layout of keys in the GUI with JSONs from the keyboard layout editor.

I use this script with a MMO gaming mouse so all the example layouts/keymaps are 12 keys long and the layout is just a 3*4 grid.

Let me know what you guys think. The code is rough but I enjoy the experience it delivers.
