Key Modifiers and Shortcuts for the Stage

On both the Input Selection and Output Transformation stages, there are several shortcuts, key modifiers and contextual menus to help you move and reshape your slices.

General Shorcuts

  • Ctrl-Z and Ctrl-Y (Cmd-Z and Cmd-Y on a Mac) undo and redo your last steps.

Key Modifiers

  • Hold down Shift while dragging to constrain movement to either the x or y axis.
  • Hold down Alt while dragging to make a duplicate.
  • Hold down Ctrl while dragging to temporarily disable snapping.
  • Hold down Shift while scaling slices to constrain aspect ratio.
  • Hold down Alt while scaling to scale from the center, rather than the opposite end.
  • Hold down Shift while rotating to constrain rotation to 45 degree angles.
  • Ctrl-= and Ctrl– (Cmd-= and Cmd– on a Mac) zoom in and out.
  • Mouse scroll wheel zooms in and out.
  • Hold down spacebar while dragging to pan around the stage.


  • Use the keyboard arrow keys to nudge 1 pixel at a time .
  • Hold down Shift while nudging to nudge 10 pixels at a time.

Slice Shortcuts

  • Duplicate with Ctrl-D (Cmd-D on a Mac).
  • When first using Alt-Drag to make a transformed copy, Ctrl-D will then duplicate and repeat the transformation.
  • Backspace deletes the selected slice(s).

Mask and Polygon points

  • Double click anywhere on the path to add a point there.
  • Double click a point to delete.
  • Shift-click a point to add/remove it from the selection.

Contextual Menus

These differ per item, but generally will let you quickly access frequently used scalings and positions.

  • Center X centers the slice on the x-axis.
  • Center Y centers the slice on the y-axis.
  • Mirror X places the slice exactly on the opposite side of the center x-axis.
  • Mirror Y places the slice exactly on the opposite side of the center y-axis.
  • Left half, right half, Bottom half, Top half scale the slice to exactly that half.
  • Whole Area scales the slice to the whole stage.
  • Make Triangle creates a triangle shape that fills the entire stage.
  • Make Circle creates a circle shape that fills the entire stage.
  • Match Input / Output Shape will let the slice take the position and shape that it has on the other stage. This way you can quickly match aspect ratios and positioning on the Input Selection stage to the Output Transformation stage or vice versa.
  • Bring Forwards/Backwards moves the slice up or down in the slice stack.
  • Duplicate duplicates.
