The uimenu item that sets the Figure
colour to the default has its “accelera-

will be executed; in this case the Figure
will go to its default colour. The “Other
... ” menu item has its “separator” set
to “on”, which draws the line above its
label. A clear figure (clf) command
will clear user-created uimenus like this
one. The command colormenu is worth looking at as another example
of a simple uimenu.
