How do I change modes for the Mining Laser?

I held M while right clicking and nothing happened. What am I doing wrong?

 

These modes can be switched by holding the M key and right-clicking.
Unless changed in configs.

 

Well, it was already set to M but for some strange reason, it didn't work. Had to switch to V in order for Mode Change to work.

 

Try going into the controls menu ingame and changing your "mode switch key" to something other than M. Rei's Minimap already uses that key and sometimes interferes with IC2.

EDIT: Too slow!

 

lol, already done and I don't use Rei's. I use CJB's Mini-Map as there are better functions.
