Dave,
You will be much happier using CHIRP than a separate keyboard.? This free software allows you to assemble memory input like a spread sheet.? It allow for naming (limited by the FT817/818 display length) frequency, offset and subtones.? You can also move entries around as you see fit for memory location.? I have entered all the frequencies for FT-8, VHF and UFH repeaters and my favorite bands as well as WWV and my local airport frequencies so my grandchildren can listen to traffic while we sit on the fenceline at the airport.
