FFIV Advance – don’t know how to flee!

Sorry if this is a stupid question, but I can’t find out how to flee in FFIV. Pressing right defends, left does…er, can’t remember, but it doesen’t flee.
I just got past the waterfall cave, and I thought I’d have to restart the game due to Tellah and Rydia being out of MP. (due to the red mousses requiring fire to kill effectively). However, I finally got to the…tentacle guy, and killed it. Now I’m on the way to damcyan. I managed by slooowly recovering MP by osmosis-ing the foes.

Seriously, how do I flee?!

L and R, press and hold.

Or, as Legendary Frog said: Press the two shoulder buttons, and run away like a little girl!

or as i would say:
FLEE? in final fantasy? MADNESS! there is no such thing as "FLEE".
*random guy*: but thiefs have flee command…
me: SILENCE!

Agreed with Catastrophe. There’s no such thing as ‘flee’ in Final Fantasy.

Question answered. Thread done.
