Arguments: &key prompt title no-dialog
Waits for the user to specify two corner positions on the screen, and
returns a box made from those positions. To allow the specification of
any screen positions without affecting whatever windows are at those
positions (as might happen with a mouse click), the user must specify
each position by placing the mouse cursor at the desired position and
then pressing the control key. If no-dialog is nil then a modal dialog first appears to explain the
specification procedure to the user; if no-dialog is
true then the dialog is skipped. If prompt is
nil, then a general explanation appears in
the dialog; otherwise prompt should be a similar string that may be
customized to the particular application. title is either a string to
serve as the title of the modal dialog or nil
(the default) for no title.
