When the Index tab is displayed in the left panel of Help, the search
field is labeled with the prompt "Type in the keyword to find:". The
'w' is underlined, which generally means that Alt-W will select the
input field.
However, when I type Alt-W from within Help, it closes POV-Ray, leaving
the Help file active. I'm curently running beta 4, though I noticed it
in beta 2 as well.
