I know there are dictionaries for apps on a mac (for applescript) that have commands. There is a dictionary for the Mail app so you can send mail etc. through applescript. Does anyone know if you can download a dictionary like these and add it to applescript so I can use those commands? If so, do you have a website? Thanks a ton!
PS: I dont really wanna use shell scripts 
ThunderBird
Itâs been a while since I worked at that level, but as I recall, an app is either scriptable or itâs not. When we write OS X apps they are not automatically scriptable. So no matter what you could download, if Thunderbird isnât scriptable, then you are stuck with GUI scripting (if even that - I donât recall if GUI scripting has to depend on some feature of the Mac OS X app. I donât think it does.)
To tell if it is scriptable, just drag the appâs icon onto Script Debugger (or Script Editor if you donât have the fabulous Script Debugger).
Whats GUI scripting?
Ok, well I dragged it onto it and it came up with a dictionary with âStandard Suiteâ âText Suiteâ and âType Definitionsâ. So would there be a way to add another suite with functions for thunderbird in it (I believe the ones it has now are the basics)? Thanks
