Known limitation: Keybinds for mods that aren't present in all instances may reset when switching between a modded and unmodded instance. This is a Minecraft limitation and cannot be fully fixed without putting in a LOT more effort into this.
This issue has been fixed in the 26.1 (and up) version
Probably doesnt work on linux
