    keybd_focus, on_off  

By default, graphics windows set a window manager hint which  
allows them to accept keyboard focus.  With ON_OFF zero, that  
hint will not be set when a new graphics window is created.  
This causes the window manager to refuse to offer keyboard  
focus to the graphics window -- very desirable, since it can't  
accept keyboard input anyway.  With fvwm, for example, this  
means keyboard focus can stay in the terminal window even when  
you are mouse zooming the graphics window.  However, many  
window managers confuse colormap focus with keyboard focus, so  
if you set the private=1 colormap in the window function, you  
may not be able to convince the window manager to give the  
graphics window colormap focus since it won't give it keyboard  
focus.  Weird.
