The "Toolbar" can be unlocked by:
1) Right-Click in any "grey" space on the screen. Grey space, is space where there are no buttons or charts. See example below.
2) Click "Customize Toolbar." In the next screen (see below), make sure the check-box next to "Navigation" is selected, then click "Close"
You'll notice that a bar at the top of your screen will appear.
That is the first step!
