Hi,
I've attached a playable macro for you to try. Import it into Macro Express and set the activation to Ctrl+Alt+A. Have a look at the workings before you activate it.
The macro should copy highlighted text when activated. It will then flash up a box to show you what it has captured, save the text to a .txt file (in a folder called 'Saved Text' in the root of C) and empty the clipboard.
The next time you activate it, if no text is found for the clipboard to copy, it will type out the contents of the saved .txt file. If there is something for the clipboard to copy, the .txt file will be overwritten with the new information.
I've only tested this in a MS Word document. It works ok but you might find that some other programs will interfere with the process.
I hope this gives you something to develop further. You might also want to add a 'Clear Clipboard' command right at the start of the macro.
Regards
Rick
