Several EditBox keys differed from 1.12.1:
- Up/Down did nothing in a multi-line box;
- Home/End went to the text's ends;
- `HighlightText` and Ctrl+A moved the caret;
- focus did not restart the blink;
- a non-digit kept a numeric box's selection;
- Option+Up could not recall chat history on a Mac.
In 1.12.1, Up/Down move a wrapped row, keeping the letter column (`0x77cb20`), or recall history in a single-line box with any modifier but Shift. Home/End stop at a newline (`0x77c980`, `0x77c9f0`). `HighlightText` writes only the selection (`0x77cca0`), and Shift extends by `0x77cd10`. Focus restarts the blink (`0x77dd68`), and Insert deletes the selection before its digit test (`0x77bf41`).
benilla now does each. Down onto the last row lands at the end, and history stays shell-style, both deviations.
Tests cover each key, in the engine and the stock mail and ticket boxes.
