// Here's the state machine we need to verify:
// (no range, press 'v') -> sticky range
// (no range, press arrow) -> no range
// (no range, press shift+arrow) -> nonsticky range
// (sticky range, press 'v') -> no range
// (sticky range, press 'escape') -> no range
// (sticky range, press arrow) -> sticky range
// (sticky range, press `<`/`>` or `,`/`.`) -> sticky range
// (sticky range, press shift+arrow) -> nonsticky range
// (nonsticky range, press 'v') -> no range
// (nonsticky range, press 'escape') -> no range
// (nonsticky range, press arrow) -> no range
// (nonsticky range, press shift+arrow) -> nonsticky range

// Importantly, if you press 'v' when in a nonsticky range, it clears the range,
// so no matter which mode you're in, 'v' will cancel the range.
// And, if you press shift+up/down when in a sticky range, it switches to a non-
// sticky range, meaning if you then press up/down without shift, it clears
// the range.
