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, close open panels (Adjust Colors, Layers, Pointers and the rest; pinned panels stay), or deselect.

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

Press M for Box Select (press it again to switch between rectangle and ellipse), L for Polygon Select, W for Magic Wand, or V for Move.

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

Press C to open or close the Auto Crop panel and review trimming the empty canvas around your artwork. Your tool stays as it was. See Auto Crop.

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 delete all pixels inside the selection on the active layer, the same as Delete Pixels in the selection bar.

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 a change waits for Apply or Cancel (an image or pointer being placed, a rotation preview, a Hue, Tint or Recolor preview, or a warning that a move, rotation, scale or smaller canvas would clip pixels), press Enter to apply it or Escape to cancel it. Other shortcuts wait until you do; zoom shortcuts still work. While picking colors with the eyedropper, Escape stops picking and keeps the preview. Enter on a focused button presses that button.

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

• Line Tool: Snaps to flat, upright, 45° or the pixel-art slopes 1:2 and 1:3, with even steps from where you started.
• Pencil Tool: Turns the stroke into a straight line from where it started, snapped the same way.
• Polygon Select: Snaps each new point's edge the same way, from the second point on.
• 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.

With the preview focused, hold Space to see the original, and release it to see the change again. While reviewing, press Alt + ↑ / ↓ to move to the previous or next changed cursor.

With the frame strip focused, press ← / → to step one frame, or Home / End to jump to the first or last frame. Scroll the mouse wheel over the strip to see more frames.

Press Escape to stop picking an ignored color from the artwork. In this window Escape never closes it or throws away a batch; use Cancel or Discard Batch instead.
