remapping vehicle controls

With 'vehicle' i mean anything that mounts me besides my regular mounts (like the joust wolf, etc) and comes with a special control bar. They use always the 1234... keys to control/fight. Now I've set up my macros as follows:

1 all chars target zenga
2 all chars target vasco
3 all chars target trejo
4 all chars target ugolin
5 all chars target poison

I never really needed any synergy when i was mounted on a vehicle between my chars, i usually did the quest just 5 times. But ToC requires me to change target when the first is killed and then assist. As u yse tab and a hotkey to the left of tab this gets complicated (for me). After all i'm not a piano player.

If this was just for 1 quest i'd change my stuff and revert back afterwards, but since I plan to farm ToC for a long time to gear up all my toons that doesnt look very handy to me.

So long story short: is there a way to remap the vehicle control keys to something else? (so instead of 1234 i'd go for azerty for example). If so ... how?

I would probably go with something based off of the F-keys, for targeting your team.
That is the default settings.
And you can invite in a fixed order if you want.

The 1, 2, 3, 4 etc DPS keys, will be for DPS in every vehicle you use.
But you could as easily map the keys to A, B, C and D.

In the end, it doesn't matter which way you go, as long as you know your system.

Thanks for reply. I installed bartender4 and decide to start from scratch, that is kicking out useless add ons & rebind all keys/actions. Better tabula rasa than staying with a messed up interface.
