Inserting in place of a selection

[gasparl]

In your current implementation, insertions can only be done if the cursor is placed somewhere in the document and nothing is selected. This is fine by me, but, FYI, I wrote a custom function that should work with selections too. I can't guarantee it's 100% bug-free, but still the option is there.

Yeah seems like a good option. Can you get rid of the commented out code and add a little bit more commenting about how it works? Like what the elements are and why they're there and why you need to loop over them.

And then make a PR. Thanks!
