The column navigator serves several purposes.

Accessing your columns

Each bar in the navigator represents a column in your main TweetDeck window. Click the bar in your navigator to go directly to that column without having to scroll. Very useful if you have more columns than will fit on your screen.

Viewing column information

Hover over one of the columns in the navigation bar and you will see some information about the column.

Here you will see:

• The column name
• The icon of service it is related to (Twitter, Facebook etc)
• The account attached to this column (where appropriate)
• How long until the next update to this column (where appropriate)
• Current API usage for this account (where appropriate)
