Is there a way to move a window without the mouse? Since installing Mavericks whenever I open a new window in XQuartz (say gvim) it positions the newly created window at the top left of my monitor.  Because every monitor now has a menu bar, the menu bar covers the title bar of the new window.

This means I can't use my mouse to grab the title bar and drag the window to a new position.

Are there any ways to drag a window using the keyboard, or failing that a way to click on any part of a window to start a drag operation?
I upgraded Xquartz and the problem went away.  Windows open below the osx title bar now instead of underneath it.
