I was thinking if there is one word for scrolling left or right. Usually we say scroll if the action is moving a mouse wheel up or down. What if we are moving it left or right? Is it again scrolling??

Reference: Definition from Google: Scrolling - noun - the action of moving displayed text or graphics up, down, or across on a computer screen in order to view different parts of them.

Definition from Techopedia: Scrolling is the sliding movement of images, video or text across a display screen either vertically or horizontally. Scrolling can be done with or without user intervention.

The term horizontal scrolling seems to be widely used to describe the action of scrolling horizontally.

i.e.:

Horizontal scrolling.

Vertical scrolling is typically just referred to as "scrolling" as the vertical is implicit, whereas horizontal scrolling requires the inclusion of the adjective to avoid confusion.
