Cursor forward (CUF)
ESC [ N CCUF moves the cursor forward (right) by N columns. The sequence is
ESC [ N C (default N=1). The cursor stops at the right edge of the screen and does not wrap to the next line.
CUF is the relative counterpart to absolute cursor addressing. It is simple, but its edge behavior is important: moving past the right margin clamps instead of wrapping, which lets applications position safely near the edge of a pane. Wrapping is controlled by text output and DECAWM, not by CUF.How this is testedautomated

\x1b[5C (CUF 5), verify cursor column is 5 (0-based).The same probe runs against headless backends (via Termless) and real terminal apps (via a daemon launched in each terminal). This lets us distinguish parser correctness from rendering correctness.
