I'm trying to use keybinds to activate the features of enderIO helmet (sound locator/night vision.) I did a quick test and it doesn't do that for 'command' actions, just keybind ones.
EDIT: And by the way, movement keys still work after it activates, but I can't steer due to still being in cursor mode. Also using MineMenu-1.7.X-1.1.7.B38-universal in Bevo's Tech Pack
EDIT2: Manually updated to MineMenu-1.7.10-1.1.8.B40-universal just to be sure. Same issue.
