In a paragraph, I want to highlight EVERY OTHER LINE. What buttons on the keyboard do I press and hold?

I tried pressing CTRL.
I tried pressing ALT.
I tried pressing SHIFT....that will highlight everyline I click on.
And I tried many combinations.
On my laptop I'm working in wordpad. (pc)
I'm editing a bunch of lyrics and it would go alot quicker if I can do this.

On my Mac I just press and hold the command key and click on the sentences I want to highlight.
It's that easy.
