F8+Highlight

The Shift key is great with key combinations. It has so many different functions
 * F8 Highlight **

However, Instead of the old Shift + arrows (or whatever key you’re using to move around the file), try the F8 key instead.

Once you clickthis key, the highlighting function is active and you do not need to keep holding down the key.

Place your cursor at the beginning of the section to be highlighted

Click the F8 key once and let it go

Use the directional keys (arrows, home, end, page up and page down) to highlight

The highlight is “anchored” to the location of the cursor when you clicked the F8 key and from there, you can highlight in any direction.

When you no longer need the highlight or need to move the “anchor” position, just click the Esc key.

Instantly, the highlight feature will be turned off and you are back to work as usual!
