Safari Tip: Sending a URL or web page to Mail
How often do you send or receive links to web pages in your emails? You see a cool web page, you want to share it with a friend or family member, so you do something like this... You go to your browser's address bar, highlight the url, and copy that to the clipboard. Then you start up Mail, fill in the recipient and the subject, and then paste the link into the body of the email so you can send it. Click, click, click, click, click, click... well, you get the idea.
Here's a faster way! Back in Safari click the leftmost icon in your browser’s address bar - this selects the entire url. Then use this keyboard shortcut:
Shift -Command(Apple Key) - i
In one step this shortcut opens Mail, starts a new email, inserts the subject, and inserts the link into the body of the email.
All you have to do is fill in the recipient, add a personal note, and send!
Hey, what if you could send whole web page? Then use this keyboard shortcut: Command (Apple Key) - i
Command(Apple Key)-i

Once again a new email is automatically started for you, only this time a copy of the web page is inserted into the email.
