How to open topic from CHM by keyword?

[AbteriX]

How do coders do that?

I want to launch an CHM help file ... and straight go to an designated page.

I already know the default syntax:
hh.exe mk:@MSITStore:example.chm::/%KeyWord%.htm

that's OK for me .... if i know the structure of the CHM

but how can i open each stranger CHM from which i didn't know the
correct path (TopicFolder) to the html (and is it htm or html)?

Like
hh.exe mk:@MSITStore:example.chm::/TopicFolder/TopicSubFolder/%KeyWord%.htm

How do coders of IDEs or editors do that to open several different CHMs from all the syntax-languages they use?

If i google i find the default answers only, using an well known topic-path :-(

Thanks for answers.

You mind find this utility of interest.  I haven't tried it yet but it claims to open html help by a keyword as one of its enhancements over hh.exe:
