allegro

[Aaron]

HI, 
I have been looking through the manual, but I haven't found this.

I am looking for text equivalents for metronome tempo markings. 

specifically allegro largo with midi equivalents so that I could insert
a term into a score with an equals sign.

maybe as follows:
 \tempo:Allegro 8.=120 c''1 or some such.

I would like the ability to add any text to a tempo and have it display
the text but the midi play the metronome mark.

BTW is text markup the only way now to add tempo marks.

Thanks
Aaron
