[Suggestion] Advertise the Esc+F1 keyboard shortcut in the menu (to switch game → editor)

[Skeptim]

Hi,
New users do not always know the simple Esc+F1 combination to switch from game to editor.
Also, some people use the dev mode because they don't know this combination which is very easy as F1 is next to Esc.
My suggestion is to add in the menu some text like "Press F1 to switch to editor" when we are on the "Close game" option.
Example:

I can make the pull request, but that's my first time contributing to a public Github repo so I wanted to ask first.

You taught me a new thing! And proved that the hint text definitely could be useful.
