asp.net button text underline

Hello Friends,


               I have a button with access key set. I need to show users the hot key of that button, so that hot key needs to be underlined. I've tried all the available possible solutions given in the web like, putting & before text, using submit button and few others.
                & did not work on my machine absolutely. I'm using Visual Studio 2008 with IE6. I can only use IE6. If I use &, then the text displays with &.
