I would think you'd want to copy the keybinds.
And the macro's.

Macro's are stored in two places.

General Macro's:
WTF -- Account -- <Account Name> -- "macros-cache"

Toon Specific Macro's:
WTF -- Account -- <Account Name> -- <Server> -- <Toon Name> -- "macros-cache"



WTF -- Account -- <Account Name> -- <Server> -- <Toon Name> -- "bindings-cache"
Seems to be the Keybinds, the same as Escape -- Keybinds.

Not sure where to find which spells are where on each action bar.
