HELLLP! is a help file authoring tool for Word for Windows.  Designed for user
friendliness, it even keeps track of context strings so you don't have to 
(but you can if you want to).  Supports both main and secondary help windows.

Automatically generates a top level Table of Contents with Hypertext jumps to 
your topics already in place.  You add additional Hypertext jumps and popups 
by highlighting the places you want to jump from and pointing to the places you 
want to jump to.  Add sound effects and launch other programs from help files.

Add professional Windows Help Files to your programs, templates and macros.

Use Windows Help as a means of accessing your corporate manuals and other 
documents.  Make Help files from your existing DOC files.  The hypertext and 
keyword features compete with Hypertext tools costing hundreds of dollars and 
it's FREE with Windows!

Naturally HELLLP! has an extensive HELP system - its manual is provided as a 
Windows Help File!

Shareware as low as $20 a seat competing with products in the hundreds of 
dollars.

Requires Word for Windows 2.0c, 6.0 or better and the Microsoft Help Compiler
(get the updated version from the Microsoft Software Library on Compuserve).
