oh you can - just click the "gray" area (where all fs commands appears) before you select the key combination.Took me some time too...

hmmmm, Wish it were that simple...Could be something wrong as the gray area you seem to be referring to is just that, I big gray area where no fs commands are to be found...in the last firmware this gray area did have the fs commands that you mention however with firmware 1.8 I just have the gray area.I'll do some more checking later on...could be I'm doing something wrong...as usual !!Cheers,

Try going to "efis/eicas" at the main menu and select "none" - then select the correct value again.You may also try to load factory default from the main menu.
