Range Key Doesn't Work

[Charles22]

Thank you DRG, it's good to know that it was the first time mentioned. Somehow or other, I run this game almost completely from the keyboard, even battlefield scrolling. Using scrolling off the mouse just doens't work too well to my satisfaction, and the zoom doesn't work at all from there, which are probably the two most common things I would use a mouse for. I am also unaware of any other commands offhand that I can use a mouse for, since the game was especially made, it seems to me, to have been keyboard-driven in the first place (can't fire guns with a mouse etc.).
