Motivated by Don Siders' updates to lcl xml help files I began to add to the help files for TAChart, too. The new hints do show up in the code editor, and now I am able also to build the chm file from the xml files using fpdoc. But I cannot convince the IDE to display the help files when F1 (or Ctrl+F1 in classic keyboard mode) is pressed. I thought I'd have to register the new help file somehow in "Tools" > "Options" > "Help Options" > "Databases", but there's nothing to add a new package.
Any help would be appreciated.
