Pixel Mouse Reporting (1016)
SGR-Pixels mouse mode (mode 1016) reports mouse coordinates in pixels rather than cells. This enables sub-cell precision for applications that need exact pointer positioning, such as terminal-based drawing tools or image viewers.
How this is tested: Enable SGR pixel mouse (
CSI ? 1016 h), check getMode("pixelMouse") returns true.Analysis2026-03-26
