Unfortunately, this isn't quite what I need. I'll try to explain why I need this "odd" function  :D

I'm a teacher and each class I teach has its own program and its own schedule. The program is in an Excel document and the schedule is in another Excel document. The program looks like the attached picture.

When I make a class's schedule I paste each clip on a certain date. It would be very convenient if the just pasted clip would be removed from the list (or moved to the bottom), because that would prevent me from using the same clip again on a different date. After all,  I don't want my students to do the same homework twice.  :)

So that's why separating the used clips from the unused ones would come in very handy for me.

Quicktext - extremely useful.

I've been a satisfied user of FARR for a few months now. However, there was one thing that bugged me from the start: when I pressed the hotkey, FARR's window popped up, I started typing but there was nearly always a delay of a few seconds. Somehow it seemed that FARR seemed to freeze for some moments.

Yesterday I changed my AV-program from AVG Free to Avast Home (also free) and guess what? The delay was gone and didn't come back. So when you experience the same problem as I did, changing your virusscanner might do the trick for you too.

Mouser, any idea what caused this problem?
