* On `up` key down, for Macs, fix select to start of block.
* On `up` key down, for Macs, move the selection to start of the block.

* OPTION-SHIFT-UP is supposed to expand to the start of the current block
* then the start of the previous block and so on.

* On Chrome and possibly other browsers, OPTION-SHIFT-UP expands the
* selection to the start of the current block then extends the selection to
* somewhere in the previous block but not to the start of the next
* block. This problem does not appear for OPTION-UP.
* COMPAT: Certain browsers don't handle the selection updates properly. In
* Chrome, option-shift-up doesn't properly extend the selection. And in
* Firefox, option-up doesn't properly move the selection.
