问题
I see a lot of applications that can respond to applescript messages such as this one.
tell application "Safari"
return URL of front document as string
end tell
How can I query an application to find out what commands it will accept? Is there a tool for doing so?
回答1:
In AppleScript Editor, do "Open Dictionary", select the application you are interested in, and you get a nice browser that shows the commands and their documentation (if the developers have chosen to provide any).
