== Grease Pencil ==
Special request by Alxarch for Architecture:
Hold Ctrl-Key when 'Draw Mode' is enabled to draw straight lines.
Although when drawing the stroke, the stroke will still be freehand, the final result will be a line between the endpoints of that stroke. This is useful for annotations of sectioning lines + site maps, etc.
