How to on Vassel Squad leader

I may be thick, but I got a copy of Vassel and Squad Leader .jar file. I got the file to open but could find few controls. I couldn't pan or grab a counter except to draw (what I assume is a LOS) line. I am using a laptop, (no Mouse). I could not find enough in the pull down menus that wasn't grayed ot. Keyboard combo seemed to little good. The help files I found did not explain how to choose or move a unit.
I am missing something.
Are there a set of examples or instructions?
