With http://www.tesnexus.com/downloads/file.php?id=6964 you can zoom in on stuff by holding down the right mouse button to activate them and using the mouse wheel to zoom in and out. I like it a lot but would like to change the activate button as I'd like to keep the right mouse button for block. I get a bit confused by the script, though, so I'm not sure what to change. Also, how do I know which is, say, Mouse Button 3 on my http://www.logitech.com/en-gb/mice_pointers/mice/devices/4259? Here's the script in question:

Any help appreciated.

You need to change this:

if bInitialize !=1Set iMouseWheelUp	to 264Set iMouseWheelDown	to 265Set iMouseBut1		to 256Set iMouseBut2		to 257Set iMouseBut3		to 258Set iMouseBut4		to 259Set iMouseBut5		to 260set bBinequipped 	to 0set iZoomvalue 		to 90Set bInitialize		to 1endif

The buttons are specified by direct x scancodes, a list can be found http://cs.elderscrolls.com/constwiki/index.php/IsKeyPressed2. Just change the buttons you want to a different scancode. You also need to change bInitialize to 2 or the initialization block won't run again if the mod was already active in a savegame you load. Like

if bInitialize != 2Set iMouseWheelUp	to 264Set iMouseWheelDown	to 265Set iMouseBut1		to 256Set iMouseBut2		to 29Set iMouseBut3		to 258Set iMouseBut4		to 259Set iMouseBut5		to 260set bBinequipped 	to 0set iZoomvalue 		to 90Set bInitialize		to 2endif

for example should update the buttons and set the controls that were assigned to the right mouse button to left control.

EDIT: Not sure how to find out the mouse button number on your mouse (except for the obvious ones like left and right). If no one knows you could just try with a debug message to find out.

Excellent. I basically tested different scancodes and got the one I wanted on the second try. Perfect. Thanks!
