well it was more envy than anger, but i had the advantage... had not nice features to distract me.. (apart from mexes radius lines, scar marks, the cool loading screen images, and the nice black color of my army).
how bout shift+rollwheel, if you roll forward, the grid gets smaller, rolling the other way, gets bigger... this while holding shift (+alt too) and dragbuilding.
holding spacebar moves the hole build array..
well its easy to say it.
ps:i dont dare to post my mouse picture., but its a good old trekker, has a nice feeling, i cant get rid of it, even when i have a genius optical (ugly).
when i click too much with the wheel, its spring makes sounds.. haha
