# Cursor Forward (CUF)
> Move the cursor right n columns.

- **DEC STD 070:** [§5.4.4 Cursor Forward, p. 5-45](https://archive.org/details/bitsavers_decstandar0VideoSystemsReferenceManualDec91_74264381/page/n299/mode/1up)

Move the cursor `Pn` columns to the right. A `0` is taken as `1`. The cells
passed over are left as they are.
The cursor stops at the right margin if it started at or left of it, and at
the last column if it started right of the right margin. It never wraps onto
the next line and never scrolls.
Moving the cursor cancels any pending wrap. DEC STD 070 calls the pending
wrap the *Last Column Flag*, and its appendix on autowrap lists this among
the controls that should reset it
([§D.6.1, p. D-13](https://archive.org/details/bitsavers_decstandar0VideoSystemsReferenceManualDec91_74264381/page/n1199/mode/1up)); xterm clears it in
[`CursorForward`](https://github.com/ThomasDickey/xterm-snapshots/blob/xterm-411a/cursor.c#L211-L243), and libghostty-vt does the same. A cursor in the last column with
a wrap pending stays in that column, and the next character overwrites the
last cell rather than starting a new line.
[CUB](https://control-codes.page/csi/cub/index.html.md) goes the other way.
