means To move text or images smoothly across a screen, or the noun for a rolled-up length of paper or parchment bearing writing.

from From Middle English 'scrowle,' an alteration of earlier 'scrow' (a strip of parchment), influenced by 'rolle' (a roll). 'Scrow' traces back through Old French 'escroue' (a scrap or strip of parchment) to a Germanic source. So the word literally describes the thing itself: a strip you unroll to read. The screen sense — the steady upward creep of text — is a 20th-century borrowing, naming the digital motion after the ancient gesture of unwinding a scroll.
