I have written a small productivity tool that does a few string manipulations via the clipboard.
It is currently registering a hot key, where it pulls in the clipboard text, processes it, and dumps the result back on the clipboard.
I have this installed on CMD+SHIFT+V
currently what you need to do from another apppiclation is copy (CMD+C) and then activate my hothandler (CMD+SHIFT+V), and then you have to paste it back into the orginal app with (CMD+V).
I'd like to eliminate the third step if possible, so my hothandler somehow tells whatever is the active application to paste.
Any suggestions how to do this?
My code (minus the actual boring text replacement stuff) is this:
Please note this needs carbon framework for hotkey handlers
[EDIT:] I borrowed code from this answer on stack overflow for the hotkey handler code.
