Ability to use Keyboard Shortcuts to post an item update

Hello, I would like to suggest a Keyboard Shortcut enhancement. After I finish typing out my message/update it would be nice to post that message with a quick keyboard shortcut. Shift + Enter seems to make the most sense but does not work. I can hit TAB 4 times to highlight the blue “Update” button but that seems really tedious, as does having to take hands off the keyboard to hover and click the button. Anyone else experience this pain point?
