Anyone know of a copy/paste app for quick pw input?

[djdelirius]

Is there an app that enables your to basically store a given string then paste it into the selected text box input by some sort of shortcut? For ex. instead of having to type my password each time I log into my iTunes I want to just paste the password by some means of a shortcut like a gesture or buttons on the keyboard. My iPad is jailbroken too.
