Hi Kappster,
I'm actually trying to do the exact same thing as you. I think I've worked it out to a degree, but I cant seem to keep the ripple effect isolated to just the surrounding keys.
Basically what you do is first create a group within your chosen profile and call it something like "Ripple F" for example. Then assign your new lighting settings for the surrounding keys like normal.
Then to make this effect singled down to just one key. Go to the assignment tab and select your chosen key. Right clcick and select "assign new action" then at the bottom of the menu you should see a "lighting when start" section. There you can select the "Ripple F" group you just created and it will only work on that key.
As i said before though, I can't seem to keep the ripple effect confined to just a few keys, so it goes accross the whole keyboard.
Will keep trying and let you know if i crack it.
