i have uploaded a dummy skin.
this is a fully working dummy skin for button changer, just drop it into your rr skin folder ,like you would if its a new skin, then select it either from within a in the skin changer screen of a skin or change your rr config, it will not launch an other skin files like audio player etc.
but it will show the activation of the script the select and the change . You may need to change the paths in the Menu.skin, to where ever you put the script, at the moment the path is set for $rrpath$Plug in's\buttonchanger\buttonchanger.exe just change these lines .
have fun with it
just Press and hold the menu buttons and a popup should appear, make your selection and hit select.
