Sorry, I know nothing of Java. Just took some digging about Debian's alternatives system

I'm doing a little course on computer hardware design and have been wanting to run the hardware simulator on my tablet. Finally we have a Java WM that works at a good enough speed so I can get back to learning! (A year later...)

Now I just need a little bit more vertical screen space and I'm set. Is there a key I can hold to drag a window from anywhere in OpenBox? (For example, with Metacity in GNOME, you can hold Alt to drag a window, allowing you to drag its title bar off the screen).

Edit:
Aha! The Menu key does it, of all things. I guess that's mapped to Alt...
