My old mini-computer screen displayed the entire alphabet in order (followed by other miscellaneous symbols) in a rectangle with the first two rows:
Below the screen were five buttons:
At the start of typing each new word the “A” was highlighted. You then moved to any other letter, one box at a time, using the arrows and pushing the OK button to type the highlighted letter. So typing “THIRTY” could be done in 30 button pushes.
My new computer is of a similar style, but with more letters per row. Now typing LOW can be done in a dozen or fewer button pushes and there are three numbers which, if spelled out, can be done in a dozen or fewer pushes each.
What are those three numerals?
