If you find yourself checking new emails in your Inbox when your sole purpose was to write an email, this tip will help you skip your Inbox and get to a Compose Mail page directly.
The whole trick is done by this URL, which you can access if you are logged into your Gmail account:

This makes the command totally accessible just with your keyboard. With Google Chrome active, press CMD + L on OS X, CTRL+L on Windows- to go to the address bar, then e. Now press either Enter to Compose Mail in the current tab or press Alt + Enter to open a new tab.
The main purpose of this is going directly to the Compose Mail without having to open your email Inbox. The bookmark can be used from any desktop browser. In iOS, I found the app Notes to be a good way for sending emails and writing drafts also skipping your Inbox.
