Pearson Vue Onsite Exam Tips, Please!

I take the exam tomorrow.

Someone here said:

Use the highlight function to mark key words. Use the strikethrough function to narrow down your choices so you could focus on the 2 most plausible answers; this ups your chances of getting it right.

Can y'all please break down how this works? What do you click to use strikethrough, for instance? Is there a shortcut to go to the next question instead of manually clicking the next button or arrow or whatever?

I want to avail myself of any shortcuts I can to maximize my time thinking through question answers. Thanks so much!!!
