On Ubuntu, you can move a window by pressing "Alt" and clicking anywhere inside the window. It's very useful on netbooks, when a big options window can be too large to show the buttons or the title bar.
Is there a tool to do that in Windows ?
Found a tool that claims to do it : http://www.hecticgeek.com/2011/11/re-size-and-move-windows-easily-with-altdrag/
Doesn't require a tool: Alt+space will bring up the System Menu of a window, which has a Move entry that grabs the window.
