Learn to touch-type Bohairic Coptic on a keyboard layout fitted to the language.
Work in progress: the layout is in alpha testing and may still change if a better arrangement is found.
The trainer reads the keys of a physical keyboard. On a phone or tablet without one, open this page on a computer.
I built this layout from 2,268,800 characters of Bohairic text in Coptic SCRIPTORIUM. Three keys I placed by hand: the djinkim on the home row, since it makes up almost 6% of pointed text; ⲟⲩ on a key of its own, as one sound and 5.52% of letter pairs; and ⲥ on C, which it looks like. Simulated annealing placed the rest, weighing finger travel, same-finger pairs, hand alternation and finger load.
The result costs 1.68 effort per character against 2.33 for a random layout, and puts 59% of your typing on the home row.
The course starts on the home row and works outward, one key pair per card. You meet the keys, drill them, type them in real Bohairic words, then take a scored test. Continuous text comes last.
Finishing a drill opens the next one, whatever your score, and you can go back to any drill you've reached. Cards show the Coptic letters each group teaches, not the physical keys. Only the scored tests count toward the scoreboard.
Speed is in words per minute, counting five keystrokes as a word. Home row and same-finger figures are compared with what the layout predicts for real text: 59.3% and 1.78%. A figure well off that mark is highlighted.
On the scoreboard, Course is how far through the drills each person has got, and Tests is how many of the scored tests they've posted. Speed and accuracy average each person's best run on each test. Their colours run from white to green against fixed norms rather than against each other. The norms are general typing averages scaled down for a new layout in Coptic: 25 wpm and 91% sit in the middle, and 45 wpm and 96% or better glow full green.
