I have a pocket sized keyboard that I carry around in case I need to ssh in to fix something via mosh

Yes it fits into a pocket about 3.5” by 5.5”

Connects via Bluetooth rechargeable

That is sick 

There was this keyboard in the 2010s I can’t find (it might have not even shipped) that was super compact and even have some keys combined together, so it was still a full keyboard but had half the keys
