editing button value

[Code One]

I was wondering if anyone knew how to underline one specific letter in a button? I tried somethuing like:
<input type="button" value="<u>s</u>"ave>

obviously it didnt work so I tried:
<input type="button" value="<code><u>s</u></code>"ave>

and that didnt work either.

anyone know how to do that?

unfortunatly Im not finished tweaking the code, but dont worry once I am done I will post the results for you guys here!!!! You will be able to make buttons that look like the windows buttons (the ones that have something like File with a line beneath the letter F) + you will be able to assign atlkey functions to them which is very cool!!! So give me a chance to link them upright and you guys will be the first to get it!

be cool
