Satoshis are the smallest unit of a bitcoin. 100,000,000 Satoshi is equal to 1 bitcoin, 1 Satoshi = 0.00000001 bitcoin. In the future (where bitcoin is way more valuable), it would be much easier to use Satoshis as a unit of price, but unlike the BTC logo where it is the bold B with the two slashes, there doesn't seem to be a logo like this for the Satoshis unit. Can we as a community create and settle on a logo for Satoshis and start maybe test using it? It will take a while for it to catch on but it is for the better.

TLDR : Create a logo for Satoshis, the smallest unit of bitcoin, like the BTC logo and start using it.

Like the symbols for US Dollar & cents, the symbols for Bitcoin and Satoshi should be similar. For Bitcoin, currently we have a "B", with two vertical ticks each on the top and the bottom. So for Satoshi also, we can have a "S", with two vertical ticks each on the top and the bottom. The B should be in upper case, while the S should be in lower case.

They are not! I don`t have sign for bitcoin on my keyboard too, I don`t know for such keyboard that have crypto signs, but maybe there will be. not maybe for sure there will be such keyboards in near future. It would be interesting, I would buy such keyboard for sure, and many others too.
That is actually a great business idea, when you think about it a little.
