In robofont 4.2+ you can option + triple click on a component to go to its base glyph

Update for RF 4:

from mojo.UI import OpenGlyphWindow
from mojo.subscriber import Subscriber, registerGlyphEditorSubscriber

class BaseGlyphJumper(Subscriber):

    def glyphEditorDidMouseUp(self, info):
        if info["NSEvent"].clickCount() == 2:
            glyph = info["glyph"]
            font = glyph.font
            for component in glyph.components:
                if not component.selected:
                    continue
                if component.baseGlyph not in font:
                    continue
                baseGlyph = font[component.baseGlyph]
                OpenGlyphWindow(baseGlyph)

if __name__ == '__main__':
    registerGlyphEditorSubscriber(BaseGlyphJumper)
