Keyboard shortcuts let you use the application without going to the mouse. The configured shortcuts are listed in your Preferences>Shortcuts tab. You can also create custom shortcuts for mail, saved searches and tags by assigning numeric aliases to folders, tags, and saved searches.
The Mail Folder Shortcuts tab is used to create a shortcut to quickly go to your email folders and to move a message to that folder.
For example, you have a folder called Holidays. You select the Holidays folder and assign 3 as the shortcut. From anywhere in your mailbox, typing v3 opens the Holiday folder in the Content pane. From any where in your mailbox, selecting an item and type .3, (dot 3), moves the item to the Holidays folder.
The Saved Search Shortcuts tab is used to create shortcuts to quickly access Saved Searches. You select a saved search and assign a number to it. For example, if you assign 3 to your favorite search, then from anywhere in your mailbox, you can type s3 to quickly run that search.
The Tag Shortcuts tab is used to create shortcuts to quickly access all items with a specific tag or apply a tag to a message or contact. You select a tag and assign a number to it.
For example, you have a tag called Follow Up Daily. You select this tag and assign 3 as the shortcut. From anywhere in your mailbox, you can type y3 to see all items marked with Follow up Daily. Select an item and type t3 to tag that item with Follow up Daily.
You can assign any number as a shortcut, but the same number cannot be repeated within a shortcut tab.
Click Add Shortcut and then click Browse to select the folder for the shortcut.
Assign a number as a shortcut to the folder.
Click Save.
