"you have to iterate over all the icons". I'm working on this by iterating all icons \
and finding the nearest one to the current selection according to the key pressed, \
but the code is getting really complex in terms of calculations. I was wondering if \
there is any other way of doing this? If anyone has an idea, please let me know. Till \
then I'm working on it.
