Orca Few questions

["Juan Hernandez" <juanh cox net>]

I have been using orca a bit.

I would like to know, when trying to access the menu bar in a application,
is the only to access it alt+(letter of menu activator) ie: alt+f, in
windows one can hit alt and use the left errows to move left-right, and
up/down to open a menu.

I want to know is the best way to navigate a menu bar is the flat review
mode?

Thanks
