With Enso Map Anywhere you can select an address, hold down the Caps Lock key, type "map", and a Google Map of the location will be inserted into your document. This is one of a number of add-ons to Enso Launcher, which provides the Caps Lock trickery. There are some amazing capabilities in this system.
I am particularly intrigued with the Enso TeX Anywhere add-on. It provides the "render tex" and "unrender tex" commands. If you are working in Microsoft Word, you can type in an equation or expression in TeX, and then have it rendered correctly and inserted into Word. If you need to make changes, you can restore the TeX markup, edit it, and then render it again. The only requirement is that you need to be on the web to use TeX Anywhere, unlike most of the other add-ons. This seems like an interesting way of adding power to your computer.
Even though it is all free, I have not installed it yet. I need to think about it a bit more before I decide whether to try to integrate this into my computing habits.
