there are some really good copy-and-paste apps that will store whatever you cut/copy into the clipboard, and allow you to scroll through and paste from it.
Like Clipper Plus
, from which I use their ‘Snippets’ to provide emails, logins, account numbers, you name it. It was one of the first apps I bought and can’t imagine droiding without it.
Store repetitive pieces of text in Clipper as clippings and copy them whenever you need to.
