The full help file for Triton-EditPro is not included in the editor's full setup because of a large file size.
You can download it from here (17 Mb)
To install the full help file, you will need to extract the program from the triedphelp..zip file, and place it in the folder that contains the editor. On a normal installation, this would be c:/Program Files/ - you will overwrite existing TRIEDPRO.HLP file. Help file topics are accessible from within the editor by either pressing the F1 function key or clicking on button. The TriEditPro version 2.5.1 or later has all help topics mapped to a corresponding editor windows.
