I remapped the light level toggle in 3D mode to CTRL+L (which is the default for last selection), and I remapped 'last selection' to ALT+L but the keypress combo in the menu entry does not change to reflect this remapping. I didn't check other keyboard combos on remapping, so this may apply to others too.
In the meantime the main menu bindings got fixed, but the operation menu still doesn't update its shortcut key display. Anyway, I'm really thinking on how to improve this.
