The Pen Tool allows the user to add freehand notes and drawings to the Graphics View. This makes the Pen Tool particularly useful when using GeoGebra for presentations or with multimedia interactive whiteboards. To add a freehand note onto a region of the Graphics View, start drawing while keeping the left button of the mouse pressed. Release the mouse button to finish.
GeoGebra stores the notes you traced in the Graphic View as a polyline (assigning the name stroke to it), so you can apply to it any operation applicable to the related object (move, rotate, delete, etc.).
The default colour of the pen is black, but you can change the pen properties (colour, style, and thickness) using the Styling Bar, selecting the black triangle icon displayed on the Graphics View title bar.
Erasing
To erase a portion of your notes created in the Graphic View with the Pen Tool, press and hold the right mouse button while moving it on the notes you want to delete. Release the mouse button to finish.
In order to delete the stroke you previously created, erase it totally, or use the context menu of the object, or just delete the corresponding item in Algebra View.
