I needed something that works like the notepad++ multi-highlight feature (that supports substring matches). This one can highlight the visually selected text and if there's no selection, the string under the cursor.
There is a scope for improvement. Can someone add a patch to search the current highlighted string under the cursor forward and backward with n and p?
