If you hold down the SHIFT key during this process, the direction in which you can move the element is restricted to the major axes of the current grid and the horizontal axis.

The extent of a Bézier path can be changed in a number of ways. Firstly, you can move a Bézier point. Click it with the arrow cursor and move it while holding down the mouse button. Secondly, you can change the curve profile by moving the handles. Do this by clicking a handle point and moving it to a new position while holding down the mouse button. In the same way as when you generate the points, the settings for Grid Snap, Element Snap, and Grid Alignment are also applied to any changes you make.

You can convert a corner point into a curve point and vice versa. Do this by selecting the Arrow tool from the toolbox. Then double-click on the relevant point while holding down the ALT key. After a curve point has been converted into a corner point, the orientation of each of the adjacent handles can be set separately. When converting a corner point to a curve point, the orientation of the handles does not change initially. Only when you move one of the handle points does the other handle snap in the direction of the handle you have moved.

You can delete an already drawn handle. Select the Arrow tool from the toolbox. Then double-click on the relevant handle point while holding down the ALT key. The related Bézier point will be converted automatically to the corner point.

You can add missing handles to a Bézier point. Select the Arrow tool from the toolbox. Holding down the ALT key, click the Bézier point and drag out the handle.
