GP Primitive Tools
Introduction
https://www.youtube.com/watch?v=dBpbtCQSGUA
The Primitive tools allow you to draw and edit Grease Pencil shapes. The tools generate GP strokes and are drawn using the selected Grease Pencil Brush. Not all Brush options are used by these tools.
Tool Types
**Line tool:**Use this option to draw lines. The E-key can be used to extend the line. Press Enter or MMB to confirm. Use RMB to cancel.
**Arc tool:**Use this option to draw a 90 degree arc. The height and shape of the arc can be adjusted using the control point. The E-key can be used to extend the curve with a new segment.
**Curve tool:**This tool draws curves based on two control points. This is like a bezier or cubic curve. The shape of the curve can be adjusted using the control points. The E-key can be used to extend the curve with a new segment.
**Box tool:**This tool draws rectangles. Squares can be created by using the Shift button to constrain the rectangle.
**Circle tool:**This tool draws circles. Perfect circles can be created by using the Shift button to constrain the rectangle.
Options
Edges: Primitives are generated using a varying number of points or edges. This can be controlled during editing using the mouse wheel or plus/minus keys.
**Thickness profile:**The thickness profile is a curve available in the toolbar which determines the size of the stroke from start to finish.
Workflow
The primitive tools operate in a Draw > Edit > Confirm workflow. Once the primitive shapes are drawn and confirmed the resulting strokes can be edited or sculpted like regular GP strokes.
Draw: Click and drag to draw the initial shape. Use the Shift key to constrains the shape to a square or 45 degree direction. The Alt key can be used to change the origin of the shape.
**Edit:**The start and end points of the shape can be moved. The G-key can be used to move the shape. The F-key can be used to change the size of the current brush. The Arc and Curve tools also provide additional control points which can be dragged to change the shape of the curve.
**Confirm:**The shape can be confirmed by pressing the MMB or Enter. Once a shape is confirmed it can't be edited. The stroke can be deleted by using Undo.
**E-key:**Used to extend lines and curves with new segments. Only the last segment can be edited.
**G-key:**Used to move the shape. RMB cancels the move. Left click to confirm the new position.
**M-key:**Curves only. Used to flip or mirror the arc or curve.
**F-key:**Press then move the mouse up or down to change the size of the brush. RMB cancels the operation and restores the original brush size.

@Blendify Hi, I think you are responsible for the manual but the GP section is pretty non-existent. I've made some effort to document some of the new features I've been involved in. Hopefully this helps.
