Well... which means its not really defined what the user will expectonce he push the button. Therefore we do have at least 2.5 major behaviors:- Geany is calling a browser and opening a webpage with info (spellcheck plugin)
- Its opening a message window with
       * a short info about plugin (e.g. geanyLaTeX)
       * a long help text about plugin (e.g. geanymacro)
Question is, what do we really want to have behind that function?

I think that a full help text is the best (but having written geanymacro you could argue I'm a bit biased). The reason is, that I think that a user should not have to get the source, and look at the readme file to know what a plugin does, or what the options mean. It is much more convenient for the user to have it there when they press the help button for that plugin.
