Right click, open in new tab? I’m surprised if most people don’t know this

[Dalewyn]

I implore you to see how most people use computers more, because no: Most people don't know how to right click.

Most people don't know tabs or multiple windows, either.

If with "most people" you mean people aged 12 to 30, possibly with some form of higher education, then I grant you your surprise.

However, most people are not very skilled when it comes to computers.
