Make the yanked region apparent!

map y <Plug>(highlightedyank)

If you want to optimize highlight duration, use g:highlightedyank_highlight_duration , b:highlightedyank_highlight_duration. Assign number of time in milli seconds.

let g:highlightedyank_highlight_duration = 1000

If a negative number is assigned, the highlight would get persistent.

let g:highlightedyank_highlight_duration = -1

When a new text is yanked, the old highlighting would be deleted. Or when former lines are edited, the highlighting would be deleted to prevent shifting the position, also.
