Keyboard shortcuts

Every key prism knows, in one place: first the keys on the app's own shortcut sheet, grouped as the sheet groups them, then the keys that belong to one panel or tool. Every shortcut works in both modes; the Simple ones are those Simple's sheet lists.

6Canvas

KeysWhat it doesSheet
Q · T · O · PAdd a quad · a triangle · a circle · a polygonSimple
LAdd a lineAdvanced
KAdd a mask (cuts the selection)Advanced
DDraw a shape freehand (a rectangle becomes a quad; Alt or an open stroke: a line)Simple
Shift + DPen: click for corners, drag for curves (Alt: one handle); four corners make a quadAdvanced
Shift-clickAdd a shape to the selection, or take it out (Ctrl/⌘-click too)Simple
Alt-dragSelect and drag a shape's groupSimple
Arrow keysNudge the selected shape or point (Shift: 10 px)Simple
MCurved mesh on / off (quads)Advanced
DelDelete the selected point, else the selected surface (Backspace too)Simple
EnterFinish a Pen shapeAdvanced
EscCancel the drawing or the point; leave drawing, picking or aligning; else select nothingSimple
Double-clickAdd a point on an edge (a curve keeps its shape); on a point: corner ↔ smoothSimple
Alt-drag a pointPull curve handles out of a point; on a handle: move it alone (no symmetry)Advanced

While dragging: Shift keeps a move straight, a box's proportions and a circle round. In the Pen, Backspace takes back the last point. Del deletes only with the canvas, the page or the Surfaces list focused: on a scene tile, a Live control tab or a panel's button it does nothing to your surfaces, and in Draw or the Pen it never deletes the selected surface. See The canvas, Shapes and Draw and Pen.

Source-backed shortcut reference

This table is generated from the command registry. Tool-specific gestures and context are explained above. Mod means Ctrl on Windows or Command on macOS; a shortcut may require its panel or canvas to have focus.
