how do you mkae shiria take up the entire screen?

[Matthew Elliff]

subject says it all. i just downloaded this browser and it does work  
with voiceover. my questions how do i make any aplication such as  
shira take up the entire screen like safari and mail do? zoom doesn't  
seem to do what i want. i'm still used to the windows world where you  
can maxamize a window from the file menu. does zoom the same thing as  
maxamizeing an aplication? thanks in advance for any help.
