Keyboard shortcuts are a real time-saver when you're on a computer. And they're vital for solving geocaching puzzles! Two of my favorites are Control-C to copy and Control-V to paste, along with Control-F to search for text.
But wait! There's more! Have you heard about Control-U? The Control-U shortcut shows you the hidden HTML source code of the cache page! Puzzle creators love hiding stuff in there, so it's a great shortcut to use when trying to solve tough puzzles.
How about a little practice?
Right now, hold down the Control key on your keyboard and press the "U" key. That will open up a new window filled with gobbledygook. This stuff is the source code for this cache page.
To search through that gobbledygook for the prize, click on the new window and hold down Control and press "F" to search. Now type "shortdescription" in the search box. You may need to click the "Next" button, depending on your browser. That will take you to the cache's Short Description, and you'll see the text it contains, with all of the formatting gobbledygook around it. You're almost there!
Scroll down a little farther until you see "Nice work!", then follow the instructions there to solve the puzzle.
If you get it right, the checker will give you the final coordinates, easy-peasy!

You can validate your puzzle solution with certitude.
