Enum Grain 

pub enum Grain {
    Char,
    Word,
    Run,
}

What a drag-select moves by. A press sets it from the click count the driver counted, the way every text UI does: one click drags by characters, two by words, three by whole runs.

The unit is not just a rounding of the live end — the anchor rounds too, and outwards. A double-click-drag that turns back on itself keeps the word it started in whole, which is what makes the gesture feel like it is selecting words rather than snapping to them.

Variants

Char

Word

Run

One text node’s whole content — a label, a paragraph. cosmic-text calls this a line; here a run is the thing a triple click takes. In a cells grid it is one whole row, edge to edge, which is what a triple click takes in every terminal.
