Just to check, my understanding that 'forwards' and 'backwards' are hooked up to change a seed value used for a random calculation of the fill/stroke colour choices (an almost infinitely large carousel of random choices, left or right). Where the buttons act something like the below image to maintain the current behaviour where clicking the large Xo icon still progresses forward:

Just to bring clarity to what I have implemented so far:

(1) clicking on the left xo icon or the < icon causes the color pair
to cycle to the "previous" color pair in the list of colors found in
xocolor.py
(2) clicking on the right xo icon or the > icon causes the color pair
to cycle to the "next" color pair in the list of colors found in
xocolor.py
(3) clicking on the large xo icon causes a random color pair to be
selected from the list in xocolor.py and resets the index used in #1
and #2. (Essentially the same as the present behavior).

There is also a "hidden" button (a temporary kludge) to undo (useful
for undoing the random selection). The intention is to associate a key
(Ctrl-z) to the undo function.

Of course, you can still back out of the whole thing by canceling the
changes in the manner currently supported: hitting x instead of ✓ on
the panel.

Comments on the above:

(a) The order of the colors in xocolor.py is reason to cycle through.
If you get a close approximation from random, you can fine-tune your
selection by searching through adjacent colors.
(b) I don't know how to get icons that can both be recolored and use
accelerator keys, hence the kludge above. For accessibility purposes,
it would be nice to add short-cuts to all the buttons in the control
panel.
(c) Gary, I tried the stacked icons vs running them in a row. The
stacked icons didn't do it for me (or Eben, as I recall). The current
configuration is xo < XO > xo.
