this is a nice idea; clipboard help and spell doesnt do it
BUT its a nice request for a coding snack i think; ill bet skrommel could add it to his clipboard tool in no time.
i think your idea should be added to clipboard help and spell but in a fuller way that i will put on the todo list, the ability to specify a set of rules+actions for incoming text, that would let you say "when this amount of plaintext is captured, in these apps, do this.." where one operation would be saving to file named by user, etc. i'll put that on the todo list BUT i highly recommend for your case you submit a request at coding snacks section as your likely to get a solution 100x faster.
