I agree with Grench that the number row has 4 "characters" printed on each key (and 7 on one). If we skip printing "F1" etc. on the number row (for those that have F1-F10 on those keys) that opens up the 3rd marking for a 4th character/function. I forgot how tiny the F# markings were since I never use those to find those keys. Maybe that is why some of us are ok with not including those completely on their own. Don't forget that, while the Pandora number row and Pyra keys may be similar in size, the Pyra key caps will be smaller and have less space to print everything. I am not getting into the debate over more or less characters printed per key. I have stated many times that I prefer few key markings. As for the size of dots for .:;, I don't see why they would be tiny. If they are too small the user won't be able to distinguis : from ; and ./,. I am using a keyboard with tiny little painted keys with the character area probably about the same as it will be on the Pyra and all of those are distinguishable in 2 colors at full arm length from my unassisted eyes, and I am pretty myopic. They don't take up much space on a key, so why would they be unusably tiny?
