Is your request related to a problem? Please describe.
Using the Cmd + 0 to reset the font size of gaml editor to default value.
Describe the improvement you'd like
With Cmd + + or Cmd + - we can increase or decrease the font size in gaml editor, it convenient for showing code in some demo session, then we want later to return to default font size, but it seems there is no key shortcut for current gama version (or must go to Preference to twitch, I did not test)

Describe alternatives you've considered
Obviously in eclipse, it use the Cmd + 0 to reset the font size to default.
