⌘L to Add Link...

I like to link to things when I write email and until I added this shortcut it required a left-click, menu hover, and a menu item selection. Save time and your wrist with this shortcut—now I hit ⌘L and I’m off to the races. 

Here’s how to do this for yourself:

1. Open System Preferences
2. Select Keyboard
3. Select Application Shortcuts
4. Click the ”+”
5. Select Mail from the drop down
6. Enter “Add Link…” for the Menu Title
7. Hit “⌘L”
8. Hit Add and quit System Preferences

In Mail, go type an email. Select the text you want to link, hit ⌘L, and paste in the URL.
