Took a look at the code (I wrote it, but couldn't remember how the
centering worked).  Tom is correct, it fills the blanks in with the
current center of the screen.  You can change it at will with the
input field.  It does not pick up the mouse position for the center.
One of the ideas behind this function is to set up two or more
Xastir displays identically.

Centering can be done via a middle mouse click (which also zooms out
by 2x), by using the Center function on the right-click mouse menu,
or by using the zoom level functions.

I'll certainly entertain ideas for better function labels.
