I have configured my chocobo mount to use a key on the keboard. Say G for instance. How do I go about putting that in a marcro line so it works instead?

I know you can do stuff in macro that type message. For Example:

/p Hello

and that will type Hello in party chat.

I cannot figure out how to get the g key to be used in a macro other then typing the letter g which puts it in a say line by default.

/g
/"G"

None of that seems to work. I even tried to change the shortcut to the insert key and tried:
/insert
/"Insert"

With and without spaces after the /.

Nothing seems to help.

Anyone got this working? If so please if you don't mind share your syntax for your macro line. Thank You.
