Up/down arrow keys in first/last line of text don't go to beginning/end
When the cursor is in the last line of a document or text box, standard behavior (at least on macOS) is that pressing the down arrow key moves the cursor to the end of the line. Similarly, when the cursor is in the first line, the up arrow key moves the cursor to the beginning of the line. This does not occur in MuseScore 2.1 or current development versions.
Multi-line text is not working at all in master currently, but as far as I can tell this fixes the editing behavior to match most macOS apps: https://github.com/IsaacWeiss/MuseScore/commit/4fdcc1b32f60255c86d20076… However, it does not seem to affect text editing in e.g. Format / General Style / Header, Footer. Feedback appreciated.
