There is a terrific new feature in Pages 5.2 that lets you share your document from right inside the document. The icon that allows you do so is a little box with an arrow pointing upward. It is the same icon that you use to send items in iOS 8. You will need to save the document before sending it.
If you have an iCloud account, you can send the document via Mail, Messages, AirDrop, Twitter, Facebook, or Linkedin. To use that option select Share Link via iCloud.
As an example, select Messages. A contextual window opens allowing you to move your document to iCloud. Then a Messages window opens that contains your document ready to send as soon as you enter the address(s) of recipients. The recipient clicks on the URL to get to the document.
Or you can send a copy via Mail, Messages, or AirDrop.
In this case, select Send a Copy and choose Mail. Mail will open a new message that already includes your email address and the document. All you have to do is enter the recipient and subject and hit Send.
I hope these tips help increase your efficiency and comfort when using Pages.
