/c

I want to be able to, as I am typing, copy something. In other words, I don't want to have to type something and then use my mouse to highlight it and right click and copy or control-c. Actually, I just tried something and I guess you could hold ctrl-shift and left arrow to where i want to copy.
But I am looking for something more along the lines of: hit a button (on the keyboard, maybe an F key?) to enable real-time copying to the clipboard and then hitting that button to disable it.
