Create hint for "escape" key shortcut

[jaimemears]

users dont know that "escape" is how to make the text box size responsive. Is there a way we could add a hint or something? If not, we will add some tips on the about page.

@jaimemears Pushing up an update now which looks like this: The notification won't fire every time you create a new text annotation, but once for each time you load the app in the browser (ie. a page refresh will cause the notification to appear again when creating a new text object).

That looks great. thanks @adamjarling . I will close this issue.
