keys: Re-order editor text manipulation key bindings by importance.

The text manipulation hotkeys are re-ordered to place more powerful
commands at the beginning of the category in the help menu and the doc.

As part of this process, the editor key bindings are grouped by their
categories within the source file, improving readability.

Hotkeys document regenerated.
