- The basic method to use hypertext is "hypertext IDs".
- All hypertext jumps are numbered sequentially (0,1,...) from top of
- document to bottom. These numbers are called "hypertext IDs".
- Hypertext id is passed in OnJump and OnRVMouseMove events.
- More correct, jumps are numbered as FirstJumpNo, FirstJumpNo+1,
- FirstJumpNo+2,...
- FirstJumpNo is a property of RichView, 0 by default
