Edit Bar controls: Origin, Apply.
This tool allows you to move the origin point of the current block or layer.
After activating the tool, pick a new point for the block origin. You can either choose a point from the Origin drop-down list and then press Apply or use snap modes to identify the point.
The specified or snapped point will become the current block origin.
The origin point is important because this is where the cursor is placed when you add a new block insertion.
