Is there a way in Terminal to highlight the row under the cursor? I need to read a long row of output in Terminal and was wondering if there is a way to have the whole row where the mouse cursor is positioned highlighted. Alternatively, would there be a way to highlight a row and control the highlight with the keyboard?

Thanks.
Yes - just put the cursor on the line and triple click it - and it will light up the whole line.  It works with apple terminal as well as iTerm.
