AURORA

Pinch is your one tool — quick trigger gestures switch what it currently does. No shape to hold the whole time you're working.

Hold a thumbs-down for a second to switch pinch to erase, two open palms together to switch it to drag, or a single thumbs-up to switch it back to drawing — then just pinch, no need to keep holding those shapes. Two-hand pinch still zooms. Stick out just your pinky (thumb tucked in) and circle a drawing to select it, then pinch it in drag mode to move it, or drag it right to delete. Hold thumb + pinky out (🤙) to start listening — try "clear", "undo", "bigger brush", or "change color to pink".
