Indeed and I read it, all I found there relating to keybinds was:

BindPad (Skulk)

It allows you to Bind Spells or Macros directly to Keys - without the need to place it in one of your Actionbars. That should help you alot to keep your interface tidy. It also allows you to rebuild your XKeys- or Keyboardlayout - so its a lot easier to remember which macro is bound to what key (i think its more important to those guys, who wanted to use their keypad...like i do). Keybinding is very easy, just klick the macro, hit your key, hit "Yes i'm sure" and your Key is bound....
From what I can tell this is different to what I am looking for as it allows you to add keybindings to spells / macros. I was searching for a way to extend the keybindings screen so that i can bind multiple keys through that to an action.

Again the reason for it is i'm looking to bind movements such as strafe to more than 2 keys, afaik you can't make movement macros so the sticky you posted doesn't solve my problem. Unless you can macro movements?
