Help+Manual doesn't currently have a macro or auto-text facility, but there are a lot of good programs that will give you this across all the programs you use and not just HM. I can personally recommend Phrase Express
, which I use myself -- it also has a server mode so that all co-workers can use the same auto-text database. You then just type the trigger text you have defined for your standard text and it gets inserted automatically. For example, you could define something like "cce" for "Click to Enlarge". I only use it for auto-text, but it also integrates with a free macro program called Mouse Recorder to give you macro capability as well. I haven't tried that, so I can't make any recommendations on it at the moment.
