Passing modifiers to macros

[JohnGabriel]

I made a named macro action under game helpers and placed my mount macro, then I added a keybind for it, F3.

/cast [nomounted, nomod] Imperial Quilen
!if (character is in "shamans") /cast [mod:alt] Ghost Wolf
/dismount [mod:shift]

So how can I pass the shift and/or alt modifier to the macro? Do I have to create separate keybinds for F3 , shift-F3, and alt-F3 and point them all to the same macro?

That's covered in here.
