utop key bindings / key shortcuts

utop is an improved toplevel for OCaml supporting line edition, history, real-time and context sensitive completion, colors and etc.

utop is convenient to use. However, the key bindings are a little bit different from the ones with GNU readline. What are all the key bindings?

The #utop_bindings command will print all the key bindings. Here is the output from the utop of my installation (here is a plain text version):
