Why can't I start typing, then empty the line and enter an operator as first character and get the reference to last line?
The documentation [1] states:
> 2. Type an operator (like +) immediately after typing return to start a new line:
Why is this limited to "immediately after hitting return" ?
I would like to see this also work after I started typing and then changed mind and erased everything and start my new line with an opterator.
