About two weeks ago, I released a new module: Free Alt.
In default Foundry, pressing Alt highlights all tokens on the canvas. But some modules also use Alt for some keybindings. When buttons have multiple bindings at the same time, this is not only distracting, with many tokens on the canvas, this can also mean a steep drop in performance. With Free Alt, highlighting all tokens is remapped to H, so that Alt is free for other key bindings.
