standard function close Alt-F4 in modal dialog box

hi,

does anybody know how to activate the standard functions eg "close window" (Alt-F4) or terminate transaction in a modal dialog box (a dynpro-type modales Dialogfenster(in german)) eg the flying window of the system-status.

i looked in the status of the status-dynpro, but could not find anything special about it.

hints welcome...

thanx a lot in advance. matthias kasig
