I have used two keyboard shortcuts for my main two credit cards for years. I don't live in a high-density area, and have a home office, so my sense of security is often quite different from others.

I don't have any built-in suggestions, Rodney, but I will use the opportunity to brag about one of the most under-appreciated 3rd-party apps out there, called Spell Catcher[/b">.

I use it for spell checking, sure But the real power instead is its powerful shortcut maker. I have hundreds of 3- and 4-letter shortcuts that Spell Catcher then types out URLs, entire paragraphs of boilerplate responses, 4-line signatures, complex codes that I'd otherwise have to remember, even the markup tags that are used on forums like this, such as [b][ /b], or [ /i], or [img][ /img]. Each of those three were all done with 3 letter shortcuts; but the real kick feature is that after Spell Catcher types them out, it then [i]backspaces until the cursor is right in the middle of the tags, so I can immediately start typing.

And, I use it to remember my two main credit card numbers.

One other very cool feature is [b]GhostWriter. This is a keystroke saver, where it remembers every keystroke I type, and then places those in one text file per application, per day. Again, for those that work in environments where this would be a security issue, it's probably not a feature I'd turn on. But I'm an author, and on the days when I delete a paragraph, or entire word document, that one feature has paid for itself over and over again. Saved my butt in quite a few situations.

I'm going on and on about the app, but honestly I don't work for the owner. It's simply the first program I install on every fresh Mac I own.
