How do you draw freehand in LibreOffice Writer? Is there a "pencil tool"? I have a Wacom tablet and I want to use it there.
You can try the
Drawing Bar - Freeform Line.
Or by the 'Show Draw Function` symbol in upper right if it exists.
After open the Drawing Toolbar there will be a
Freeform Line Option under
Curves and Polygons.
