How to Rotate the Canvas in Krita (Ctrl+[ and Ctrl+])

Ctrl+[ rotates the Krita canvas anticlockwise and Ctrl+] rotates it clockwise, in fixed increments, without altering a single pixel of the artwork. The numpad 4 and 6 keys are bound to the same two actions, and holding Shift while dragging with the middle mouse button rotates freely to any angle rather than stepping. **Rotation is a view transform, not an edit.** Nothing about the file changes, nothing appears in the undo history, and the image saves exactly as painted no matter what angle you left the view at. This is the opposite of Image ▸ Rotate, which genuinely rewrites the canvas and is what you want when the artwork itself needs turning. **Why painters rotate constantly.** A confident curve is easier to draw in some directions than others, because the wrist and elbow pivot comfortably through a limited arc. On paper you rotate the sheet without thinking about it. A screen and a tablet cannot be rotated the same way, so every stroke would otherwise be made at whatever angle happens to be comfortable from a fixed position — which is why long sweeping curves so often come out subtly wrong in digital work. Turning the canvas to meet the hand rather than forcing the hand to meet the canvas removes that constraint entirely. **Getting back to level is the part that catches people.** Reset is bound to numpad 5 and to nothing else. On a laptop keyboard or a tenkeyless board, the action exists but has no key, so a canvas knocked askew has no keyboard route back to zero. View ▸ Reset Canvas Rotation does it from the menu, and assigning that action a real binding in Settings ▸ Configure Krita ▸ Keyboard Shortcuts is worth doing before it becomes an irritation. Free rotation via Shift and a middle-drag is easy to trigger accidentally, so this comes up more often than the numbers suggest. **Rotation and mirroring are separate ideas.** M flips the view horizontally to expose composition errors your eye has stopped noticing. Rotation changes the drawing angle for the sake of your hand. Both are view-only and neither touches the file, but they solve unrelated problems and it is worth not conflating them: rotating to check symmetry does not work, and mirroring to draw a comfortable curve does not either. One practical note on the increments. The stepped rotation moves in fixed amounts that will not always land on the exact angle you want. When precision matters — matching a perspective line, or squaring up to an existing element — the free Shift+middle-drag is the only route that reaches an arbitrary angle, and the rotation amount appears on the canvas as you drag so you can land deliberately rather than by feel. **A habit worth forming: rotate in small steps.** Turning the canvas ninety degrees at once forces a conscious reorientation before the next stroke, which costs more attention than it saves. Twenty or thirty degrees is usually enough to bring an awkward curve into a comfortable arc, and the hand adapts to that without thinking about it. Painters who use rotation heavily tend to converge on this pattern independently — many small turns rather than a few large ones — because it keeps the canvas familiar while still meeting the wrist where it wants to be.
