Description:
When the user presses help key (keylabel HELP) when in field "nnn".
Note: The "*" wild card character can be used in place of a particular field number when using @whp, i.e., @whp*. @whp trigger can only be used on the INPUT processing table.
Field-specific events (@whp5, @whpA, etc.) take precedence over associated field events (@whpa1), @whpb2), etc.), and events including the wild card (@whp*). filePro will execute the field-specific event first, then associated field events and finally non-specific " * " events.
