Well, what do you mean by “entry”? Is each entry on a different page? Different document? How are they separated?
Also, I would need to know more about the garagesale App to help you. But as far as copying and pasting goes, you can do:
--Make sure you have "Enable access for assistive devices" checked in "Universal Access" under System Prefs, or this won't work!!!
tell application "System Events"
keystroke "c" using {command down}
keystroke "v" using {command down}
end tell
But in order to really I help, I think I need more information.
I come to think about it and it would also be ok if each entries would be copied in an application i have called CopyPaste Pro. It’s like a giant clipboard.
That would do it for me.
From that giant clipboard i would then paste manualy in Garagesale which would be not to bad.
There’s also a text app that comes with CopyPaste Pro called Bean.
