In FME 2016.1 RC, I found that the user has to click [Help] button or an equivalent command to access the help doc of a transformer. It's good for regular transformers, but custom transformers don't have [Help] button, so you cannot change the Help window to the help doc for a custom transformer while editing its parameters. [Defaults] button in the parameters dialog of custom transformers is useless, but [Help] button might be helpful.
