Hi All,
I would like to link to such a feature from within the authoring tool and here is my suggestion how this can be implemented.
We use the existing python scripts in the repo to create a new python script that only renders a single page into wiki code, which is then converted to html and put in the user's temp folder, and then loaded into the user's default browser. The python script would accept a single argument, which is the file path to the help xhp file that is to be processed.
