Selecting, moving and resizing

Selecting

• Click an object on the design area — or its row in the layers list — to select it.
• Shift-click to add another object to the selection.
• Click the empty design area to deselect.

When more than one object is selected, common properties show in the properties panel; unique properties show as "mixed".

Moving

• Drag with the mouse.
• Use the arrow keys to nudge one pixel at a time.
• Hold Shift + arrow to nudge ten pixels.
• Set X and Y directly in the properties panel for exact placement.

Resizing

• Drag the handles on the bounding box.
• Hold Shift while dragging a corner to keep the aspect ratio locked.
• Set width and height directly in the properties panel for exact sizes.

Locking

Lock a layer to prevent accidental drag or resize. Locked layers still render; they just refuse to be edited on the design area. Handy for backgrounds.

Z-order

Reorder via the layers list, or use Bring forward / Send back from the right-click menu. The renderer paints from bottom of the list up.
