Amecs is a mod that tries to improve your keyboard immersion. Therefore it introduces several modifier keys (alt, control and shift) for now to give you a larger variety to chose from when making keybindings.
Amecs also removes that annoying key blocking where only one functionality can be associated with a key.
Disclaimer: Duplicate entries will still turn red to let you know of possibly unwanted collisions.
And there's yet another feature: Amecs introduces a search bar for your controls screen! No more searching for that one nasty keybinding in a giant list.
And last but not least it adds keybindings for toggling auto jump as well as each of the skin layers.
