Is there a keyboard shortcut for saving a Snippet?

I have more than once accidentally swiped left on a Mac, effectively hitting the back-button on a browser window holding a half-written Bitbucket snippet, and consequently losing everything.  The Save button takes time to naviagate to at the bottom of the page of a large snippet, and (annoyingly) clicking it also closes the snippet.  Obvious solution -  implement Cmd-S to save the current content without exiting!  Does something like this already exist?  If not, happy to raise a Jira :)
