How do I get quick access to common text snippets? When filling out an online shopping form the other day via my browser, it sucked that I needed to manually type my email address, street address, postal code, etc.  Even credit card number (though I realize there are security implications there).

Is there a way to store commonly used snippets of text somewhere for quick and easy cut &amp; paste?  Perhaps something integrated via a soft keyboard and key combos?

This relates a bit to Share (through share menu) directly to own email address, but I want my email address to be accessible from any application.
I would put it into the keyboard's user dictionary. 

There are a few clipboard/snippet manager application, you might be interested if you need to store longer texts:
