Keyboard input for writing

[willwade]

We have some users using a TandemMaster - morse code box for writing. But would benefit from accessing phrases, messages and the webhook features in Pasco. So ideally want a way of having a typing mode - that does the features of audio cues per letter and some word prediction as they are typing

e.g.

"Spell" (activated node in pasco)
Now reads input from hardware keyboard
"C"
"A"
"T" > "Predicted words: "Cat, Catch, Catfish" (Scanned list where each one selectable)

Would need a keystroke to be able to activate a "Exit spelling mode"
