I use this:

*----------------------------
*if system menu off
set sysmenu on && to maximize preview window, otherwise short-key does not work
KEYBOARD '{Ctrl-F10}' && maximize
set sysmenu to && remove toolbox
_SCREEN.CONTROLBOX = .F. &&if close button is enabled

report form ... preview

* if needed, set back
set sysmenu off
set sysmenu to default
_SCREEN.CONTROLBOX = .t.
*------------------------
Best Wishes
