PIVOT-381 the HOME and END keys were made to work in TextArea the same way they do in TextInput, but TextPane does not work this way. Propose to make the same changes to TextPane as were made to TextArea:
HOME or Meta-Left moves to beginning of line
END or Meta-Right moves to end of line
(and SHIFT-xxx extends the selection to beginning/end of line)
And then I'd like to make Ctrl-Home on both TextArea and TextPane go to beginning of document, and Ctrl-End move to the end (with appropriate behavior with Shift-Ctrl-xxx also).
