special symbol

[Guldo K]

Hello.

I have to type a certain symbol, it's quite like <'>, you know, the one used 
mostly at the beginning of words in tex docs.
I tried Shift+' and AltGr+', and I got two different symbols, but none works.
Works for what?
I need it for musixtex.
So, is there another way I don't know to get that kind of symbol?

Thanks,

Guldo
