8.9.7 Specifying jumps to secondary windows in WinHelp
Normally jumps make the topic you are jumping to appear in the main WinHelp window, replacing the previous content. If you want to make the new topic appear in a different window, assign the Window property to the hotspot character format. For example:
JumpToExtra=JumpHot Green Window
Also add the JumpHot character format to [HelpWindowStyles], specifying the name of the target window, exactly as specified in the .hpj file:
This works for jumps, local and otherwise, but not for pop-ups.
When you specify a secondary window, you get only one instance; the next time you target that window, you replace its previous contents and leave it in place.
