what module would I need if i have options of changing buttons when you hold shift and left click? I have 2 sets of buttons and .rc files

???

...i have 2 folders with 2 different .bmp's, i want to know how to make a menu option to change between the images. I also have config files that use the .bmp's. If ur still confused ill just try to make it simple. like in Darkstar 2.4, the theme has different colors and you can change the colors my holding shift and left clicking.

Ahh...
Create two themes, use textedit to change the content of "$themesdir$themeselect.rc" and !recycle

There's a tut on doing this on ResidualVisuals. Check out "How to add color schemes" in the "Tutorials" section.
