Starts the KDE help system at the KView Handbook - you have done this before, haven't you?
Gives a short description of the item you select. The cursor changes to some sort of "help pointer". Just click on the thing you are not too familiar with and a description of it is shown.
Opens the KDE bug report dialog. If you have found a bug (and maybe know its cause and have already fixed it?) then send a bug report so the authors can deal with it.
Displays the version and the authors of KView.
Displays the standard KDE info window.
