Shift+Return to leave current code block (i.e. remove indentation on new line)

[AlexVSharp]

A simple quality of life suggestion. Someone asked about this a long time ago.

By default, the editor adds indentation (as required) once we press Return. This speeds up writing blocks of code.
However, to leave the current block, right now we always have to manually backspace after entering the new line.

I propose introducing a Shift+Return shortcut to do this automatically. i.e. Enter a new line with one (or more?) less indentation.
'Tis always one less key pressed. 👍

Note that there are already Ctrl + Enter and Ctrl + Shift + Enter shortcuts to go to the next/previous line without breaking in the middle of the line (even if your cursor is not at the end of the line).

Shift + Enter doesn't do anything different from pressing Enter in 3.5 (and it doesn't do anything in 4.0.alpha), so the proposed behavior sounds good.
