I still got 2 issues with the key-mapping, and have not heard anything for long time.
I have bound my left mouse-button to move forward, it add it to the llist but i cant get rid of "use lefthand item" from left mouse.
The new command key (mousebutton) add to the "Moveforward", instead of replace it, so i use left hand item every time i walk.
I bound middle mouse-key to interact. It have worked fine until some patches ago when i no longer could use it to close windows (machine-menus etc.). Now i have to reach "Esc" or "E" to close those menus. It work fine in other situations.
