small sub-window as a child of the window the cursor is in.  The new
window installs a cursor of size 1x1 but a mask of all 0, i.e. an
invisible cursor.  This allows you to see all the text in an xterm or

window manager and can capture all keyboard keys (ex: Power, Wake...).  It
optionally supports a Guile-based configuration file layout, which enables you
to access all XBindKeys internals, so you can have key combinations, double
clicks or timed double clicks take actions.  Also all functions that work in
Guile will work for XBindKeys.")
