Press Ctrl / Cmd + Z to undo your last paint stroke, layer move, hotspot calibration, or selection change. The editor maintains an active history buffer of up to 30 steps.

Press Ctrl / Cmd + Shift + Z or Ctrl / Cmd + Y to re-apply any action you recently reverted.

Press Escape to instantly cancel active drag-and-drop image placements, cancel the click hotspot picker, abort active polygon selection drafts, discard active marquee masks, or snap floating tool flyout panels (Color, Layers, Pointers) back to their default sidebar docks.

Press B for Brush, N for Pencil, E for Eraser, G for Fill, or I for the color Picker.

Press W for Magic Wand, M for rectangular Select, or V for Move.

Press U repeatedly to cycle through Rectangle, Circle, and Line.

Press C to open the Crop panel and review trimming the empty canvas around your artwork. See Drawing Tools.

Press [ to decrease or ] to increase the active Brush, Pencil, Eraser, Line, Rectangle, or Circle stroke size.

Scroll your Mouse Wheel directly over the central canvas to dynamically zoom in and out. Scrolling up zooms in toward the pointer, and scrolling down zooms out. You can also view exact zoom percentages in the bottom stage action dock.

Hold down Spacebar and click-drag with your mouse pointer anywhere on the canvas to pan and float the camera viewport. Releasing the Spacebar returns you instantly back to your previous drawing tool.

Press the ← ↑ ↓ → Arrow Keys while holding Spacebar (or when the Pan view tool is active) to nudge the viewport camera in 16px increments.

Press Ctrl / Cmd + + or - to zoom. Use Ctrl / Cmd + 0 to fit the canvas to the viewport, or + 1 for 100% zoom.

Press Ctrl / Cmd + A to select every pixel on the canvas. Press Ctrl / Cmd + D, or Escape, to deselect.

Press Ctrl / Cmd + Shift + I to invert the selection mask, switching which areas of the canvas are paint-locked and paint-enabled.

Press Ctrl / Cmd + C to copy active selection pixels to the clipboard. Press Ctrl / Cmd + V to paste those pixels as a floating import draft, ready to be positioned, resized, or committed on any layer or frame.

Press Delete or Backspace while a selection mask is active to immediately wipe out all pixels inside the selected boundaries on the active layer.

Hold down Shift while drawing a selection box (or using the Magic Wand) to add the new region to your active selection. Hold Alt while selecting to subtract the drawn region from your active selection.

Press Enter while plotting a custom Polygon Selection boundary to close the drawn loop back to the initial start point, creating the final selection mask.

Press Alt + ↑ or ↓ to load the previous or next cursor. Cycling wraps at either end of the Workspace list.

Press , or . for the previous or next frame. Press Enter to start or stop animation playback when no polygon or image placement is active.

While positioning an imported image, press Enter to commit it or Escape to cancel it.

Hold Shift while drawing to snap coordinates into perfectly straight lines:

• Pencil Tool: Snaps your active freehand stroke into a straight line directly from your initial click coordinate.
• Line Tool: Constrains your line angles to perfect 45-degree or 90-degree steps.
• Circle Tool: Snaps and locks the aspect ratio to draw a perfect circle instead of a skewed ellipse.

With the Select or Move tool active:

• Press the ← ↑ ↓ → Arrow Keys to nudge the active layer or selection mask by exactly 1 pixel.
• Hold Shift while pressing the Arrow Keys to coarse nudge the layer or selection mask by 5 pixels for faster alignment.
• With Move, a nudge stops when the artwork reaches the canvas edge. Press the arrow again to move past it, which clips pixels. Holding the key down never moves past an edge.
• A run of Move nudges is one undo step. Nudge back before doing anything else and clipped pixels return.
