bash - How do I reload .inputrc?

Background

I have heard that the readline module is reading ~/.inputrc and that is how it changes the behaviour of keystrokes under programs such as bash.

Question

How can I reload this after editing to see the changed behaviour without restarting my terminal program?

Answer

By default, C-x C-r is bound to re-read-init-file.

See the Bash Reference Manual for explanation.
