Funny, I usually observe the opposite use of copying at a command-line window. I often see co-workers and client users copying and pasting as little as 4 or 6 characters out of a command window, when in that case it would be more efficient to simply retype it rather than reach for and point and aim the mouse. These are tokens usually like investment account numbers or ticker symbols or the like. The excuse is usually "to make sure I get it right" -- as in many jobs, covering your ass from any mistakes is more important than actual productivity gains.

Maybe your co-workers and clientele are all skilled typists who never make transposition errors. But I've dialed enough wrong numbers due to simple transposition (mental) errors (and made analogous typing errors) to know how easy it is to make them. If 'persons unknown' had to move my personal investment account number around via data-entry, I'd feel much better knowing they were copy-pasting and not manually transcribing.
