headers in mutt

[lists at barrettpianos.co.uk]

Just received my first couple of e-mails with mutt.

Wonder if there are any options to put in the .muttrc for best 
performance with speakup?

Having a bit of an issue with the headers.

I found by googling that using the lines

ignore *
Should hide the header information


unignore From: Date: Cc: To:

Should allow those headers to be displayed.

That seems to work but now I find that the enter and backspace are 
not reading all of the body.

Instead, I get the message "top of message is shown and "bottom 
of message is shown".

Is this a mutt or speakup issue?

Also, before I added the lines to .muttrc reading the message, at 
the end of some of the lines there were percent figures, not sure 
what these are?

Thought they may have been how far through the message but 
never got higher at the end?

Thanks
