Yeah, I'm just pointing out that the up/down keys don't really zoom in an out because it could be a bit confusing.
I remember when I read that they zoom in and out and was completely confused because I would just roll "over" my troops instead of closer to them when I pressed the up key, it was the revelation that page up/page down move up and down that allowed me to zoom (thanks to combining up with page down)

Yeah, fair enough. I also didn't know about PgUp/PgDn for ages. Once you get the knack of combining those with the cursor keys it works very nicely I think.

"jerky little dots" suggest to me that maybe his resolution is really low?

[darkchampion3d]

I have a suggestion.
