Word 2016 comes with a digital highlighter pen that lets you mark up and colorize the text in your document without damaging the computer's monitor. To highlight text, abide by these steps:
Click the Home tab.
In the Font group, click the Text Highlight button.
Word is now in Highlighting mode.
Drag the mouse over the text you want to highlight.
The text becomes highlighted — just as if you used a highlighter on regular paper but far neater.
Click the Text Highlight button again to return the mouse to normal operation.
Or press the Esc key to exit Highlighting mode.
The highlight doesn't necessarily need to be yellow. Click the menu button to the right of the Text Highlight button, and choose a different highlighter color from the palette displayed.
To remove highlighting from your text, highlight it again in the same color. If that doesn't work, choose None as the highlight color and then drag the mouse over any color of highlighted text to remove the highlight.
To highlight multiple chunks of text, double-click the Text Highlight button. The mouse pointer stays in highlighting mode until you click the Text Highlight button again or press the Esc key.
To highlight a block of text, mark the block and then click the Highlight button that appears on the mini toolbar.
Highlighting isn't the background color.
The highlighted text prints, so be careful with it. If you don't have a color printer, highlighted text prints in black or gray on hard copy.
