How to zoom in and out without a mouse wheel?

[feefifofum]

Have this issue time and again with games, I dont have a mouse wheel! usually I can change the settings to use another key to zoom in and out but there doesnt seem to be an option. I personally cannot continue playing the game if I have to be so close up all the time

Sorry about that. please post in suggestions, I will add ability to rebind zoom in/out

I didn't even know you could buy a mouse without a wheel anymore.

Unfortunately trackball market is not there yet with very few 3+ button devices that also have a wheel. For example I use the Logitec Trackman Marble Mouse which have 4 buttons but no scroll wheel. For daily usage it is not as bad as it sounds becouse you just grab the scrollbar and then you have the trackball ball which is like a large wheel. Or you use page up/down or arrow keys. Or Z/X to zoom in most games.

Edit: corrected to Z/X for zooming so qwerty-folks understand what I mean :-)
