I've been using knoppix for a long time, and I never knew that Alt+F1 would bring up the start menu (lxde calls it the launcher).
Because I didn't know this, I've always had to plug in a mouse to get a program launched.
I've always used the windows key or CTRL+ESC under windows but this doesn't work under knoppix 9.1 lxde.
Now if I'm doing some system testing, I can just hook up a keyboard and be able to launch things.
For fun, I made a desktop entry in .config/autostart/reminder.desktop
