I know I've asked this before and there was some simple
hot key to switch the radial gradient from inside to outside - but
after 30 minutes of searching and trying dragging the nodes around
(asymmetrical was easy, not complete invert) So I can't find the hot
key - can someone help again ? Can this be documented better - I
couldn't find it in the hot keys list, nor under the tutorials, nor in
the "inkscape manual" - maybe it's there somewhere but not obvious (at
least to me).
