Online Help:

  Online Help in APlayer is only a Help-click away with this turned on :)

  Place the  mouse pointer on the  thing (Gadget, list, whatever) and press
  the HELP-key.

  Remember that to show the online help, APlayer needs the APlayer.guide to
  be  in  "progdir:docs/APlayer.guide" That is, it has to be in a directory
  placed along with APlayer called "docs".

  If you have used the APlayer installer to install the program, everything
  should be placed correctly and you won't have to worry about it.
