Example, I want to say something like "manual highlighting," to differentiate between highlighting something on the screen. A word to describe the process of using an actual yellow highlighter (a physical object). Is there another word for this?
You can use highlight:
To mark (important passages of text) with a usually fluorescent marker as a means of memory retention or for later reference.
- The spelling mistakes in the text had been highlighted in green.
- countable noun
A highlighter is a pen with brightly-coloured ink that is used to mark parts of a document.
