PuTTY Shortcuts to Minimize, Maximize, Restore, and Move the Window

The Alt+Space command doesn't work on Putty (at least for me). So, if I've to minimize or maximize my PuTTY windows, I'll have to use the mouse which is very uncomfortable. Did anyone get around this problem?

Thanks for your time!


Never mind, there's a setting for that.

Window -> Behavior -> (System Menu Appears on Alt+SPACE checkbox)
