A program that tracks the mouse gets its clicks, drags and moves over its grid, in the format it chose; Shift keeps pardes's select, execute and look, and chrome is never the program's

Presses and releases under 1000, drags with a button down under 1002,
every move once per cell under 1003, X10 presses under 9, in raw terminal
input only. A press the program took keeps its drag and release, reported
clamped to the grid's edge wherever the pointer goes. The press also makes
the pane the active one. docs/tags.md says so.
