Lasso
The box a drag on empty canvas draws: a 1 pt intent-green hairline over a faint fill, and a graphite readout under it counting what it will select (● 3 blocks). The same on screen at every zoom.
Use it for
- A drag that starts on empty canvas (the Select tool, or no tool). Every object the box touches is selected when the drag ends.
Don't use it for
- Showing a selection that already exists (that is the Selection frame), or a region (a region is an object you made).
