open editor ... soing it wrong ?

Hi.

when i have a region selected i used '(nuendo7) to hit ENTER to have the key editor or waveform editor open to the size i wanted.
now it opens the lower Zone … i like lower zone but i would like to be able to chose wich one i go for.
in keycommand “Editors OPEN/CLOSE EDITORS” does the same as “Window Zones - show/hide Lower Zone”
now if i want key editor in full screen i have to open lower zone then clic "Open in seperate window/Lower zone

is there a better way to do that ?

Preferences -> Editors

of course wonderful !! thx
