This tip requires that you have an email address setup and working in Apple's Mail application and can only be used in the Safari web browser.
In the good ol' days of sending interesting links to a coworker, friend, or family member you would simply cut and paste the URL for the webpage into an email, attach a funny message and you're done.
One of my favorite shortcuts in Safari is the ability to quickly take any webpage I'm viewing and email the contents of that webpage, links, images and all.
You can do this through the menu by visiting File in Safari's menu and choosing Mail Contents of This Page. If you are familiar with the Mac OS then you'll also notice the shortcut keys next to this menu item.
