There is a button for the part (the one that says "[multipart/signed]")
and the help text is associated with that. There is no button
specifically for the signature (because no processing of the signature
took place).

It wouldn't be complicated to add a button in the case where no checking
was done. Pressing the button could (as suggested) offer up
customisation of the variable (or just open the help).

I wonder if I could make the button be "[Danger Will Robinson!!!]" in
flashing red and yellow text...
