Of course there is. People typically don't know that a mouse wheel is
a middle click. I've had to teach this to several people. Not all
touchpads allow two-finger swipes, and on those that do, not all
people know that this is possible.

There is old research against it:

Ten years later, there is still some flak against it:

There can be clear indication of line numbers on the left side of the
display that shows that there isn't an actual hard newline here. It's
just a convenience of presentation.

Ah, the IDEs scroll horizontally, the text editors don't. I see why
we're coming from different perspectives here.

No, I leave it on.

Pastebin does:
