I found another one: when editing stuff in the REPL, I am often "done"
and want to execute the expression. Unsurprisingly pressing [Enter]
in the middle does not work as it inserts a newline. I have to go back
to the end of the expression to execute it.

Would it be possible to add, uhm Ctrl+Enter to evaluate the current
expression directly, without the need to go to the end of the line?
