Shortcut to insert / paste email address? Is there a way to setup a shortcut to insert my email address when typing?

About once a day I need to type my email address on some login form or order page. It would be really nice to have a kind of paste function that inserts my email address.

Of course this is also a feature request: Long (context) tap while typing - cut/copy/paste/select menu pops up -> in that menu I would like to have an additional item: "Insert email address". Even better: Allow me to define additional "paste items".
Built in to the operating system is text replacements, so if you open Settings -> General -> Keyboard -> Text Replacement you can add your own text replacement shortcuts. For example, you might add "e@" and have it expand to your full email address, such as "email@domain.com". It will automatically expand when tabbing away from a field or hitting the space key on your keyboard.
