“Save” and “Undo” Emacs-like messages with Sublime?

[jrzaurin]

I posted this question in stackoverflow but did not get any (useful) answer. Perhaps here, a more dedicated site, I have better luck

Within emacs, when one types ctrl+x+s (or Cmnd+s) but no changes need to be saved one gets the message:

(No changes need to be saved)

Also, when undoing changes and you get to the 1st change made in that session, one gets the message:

No further undo information

I was wondering if (and how) is possible to set these messages when using sublime text 3.

Thanks!

If the file has been modified, the close button in the tab changes shape. This is always visible and you don’t need to hit cmd+s to see it.
For undo, it seems like if you hit cmd+z and nothing happens, then you’re at the bottom of the undo stack. Is there a reason you’d like a specific message?
