Aha! I thought about this but I never tried it...

Can you please direct me to where in the documentation this is specified!

This function is almost what I need. I would need to be able to write
{
        < e' \meTrans a'\5 "A" \meTrans cis'\6 "F" >2. e'4
}

Which doesn't work. Since \5 isn't a pitch it's a string-number (Yes I'm 
doing Tab)

It doesn't seems like a'\5 counts as a ly:music. Just the a' is the 
music and \5 is a string-number.

If it's possible I would like to have one function only.
I have already made some shortcuts that has the txt param as a constant.
So I can call
\pedA c'

Where pedA =
#(define-music-function (parser location mm)(ly:pitch?)
          #{ \pedalAction "A" $mm #})

In the real code I have switched the params and meTrans is called 
pedalAction

so the music above will be written
< e' \pedA a'\5  \pedF cis'\6  >2. e'4

(Yes, I'm still fiddling with my Pedal Steel Guitar Tab mode)
