I assume the OP likes working in the terminal because like working with a keyboard. If that's the case, they could use the old Windows version of 1-2-3, which was optimized for terminal users by allowing all the old slash commands, but can use the full screen. They could even use an old Windows version of Excel, which also supported the Lotus slash commands, to help transition users over.
