Highlight Current Line Added
You can set a preference to highlight the current line, that is, the line with the caret
(also called the blinking cursor). This is useful, for example, to help you see where copied
text will be inserted when you paste. To highlight the current line, select Preferences
> Editor/Debugger > Display and under General Display Options, select the check
box for Show caret row highlighting. You can also specify the color used to highlight
the line.
