window scrollback [<lines>]

This operation sets how many physical lines of output is retained in the window's scrollback buffer before it is discarded. This buffer is distinct from the window's lastlog buffer.

The scrollback grows without limits when the Scrollback View or the Hold Mode View is active. The size of the scrollback buffer is trimmed back to this value when your views catch up to the Normal View.
