Allow shift-enter in edit code to add a line break instead of executing prompt.

[jurmous]

Describe the need of your request

I often want to have a multiline example in edit code like an instruction + a code example in the edit code window. For this I press shift-enter. Currently it immediately executes my half written prompt. I would like it adds the line break.

Proposed solution

Add a line break in the edit code window when pressing shift-enter instead of starting execution of the code edit.
