BeamAlertHack - This hack eliminates the annoying alert which pops up after each beam (appears, if you have turned off 'beam receive' in the palm preferences).
The creation of this hack is so obvious, that I suppose somebody else has already written a hack with the same function
EnterHack - This hack is useful for persons who like taking graffiti shortcuts to navigate through palm programs.
With EnterHack you can enter a 'linefeed' stroke (the one from upper right to lower left) in the graffiti area to close the active form
