In Photoshop and many other programs, the bracket keys  are used to increase and decrease the brush Radius respectively
Does Blender's Grease Pencil have this functionaltiy? I can't seem to find anything of the sort in the User Preferences.
If nothing exists, how would I go about creating it?
tool_settings.gpencil_vertex_paint.brush.size, but it will popup a ring like 'F'. $\endgroup$
