Photoshop Woes

I have a problem I can't find a solution for anywhere on google...

I need to delete the shortcuts Photoshop stores by default, preferably every single one of them.

Alternatively I need to be able to overwrite keys in Photoshop... which doesn't seem possible (PS won't overwrite them).

Anyone...?

I fixed it in another way.

It was for my Cintiq, which has a limited number of buttons on its interface. I did a "hack" where I made some of the buttons act as two different buttons to accomodate for this (i.e. the make brush smaller button also calls the brush tool afterwards) and remade other shortcuts to fit. The amount of stuff you can put on is pretty good when you're smart about how you set your configs

I used nothing but PS's key config and the same for the Wacom
