Bring content in REPL back to Code Editor: reverse the direction

[ipstone]

Sometimes new functions, or tests are defined/tested in REPL terminal, for which we may want to create as new function definiation, or bring the block of codes back to the editor window.

Current I mostly do this manually - copy and paste, but not sure if there's an easier way (such as shortcut key) to bring the 'experiment' code evaluation in the REPL back to the Editor (either at current cursor location, or top, or end of the file).
