Below the main menus you will find the main toolbar of the Main Display window.

Image 1: Main Toolbar (Default)

Many of the more commonly used features of McIDAS-V can be accessed here. Hold your mouse over a toolbar button to get a popup tip on what that button does. The main toolbar is user configurable. Right-click on the toolbar to change the icon sizes and select "Customize..." to open the User Preferences' Toolbar Options tab where you can add, remove, and change the position of the buttons in the toolbar.

You can also undock the main toolbar from the Main Display window by left-clicking and dragging the textured area on the left side of the toolbar. This will place the main toolbar in its own window. To dock the toolbar back into the Main Display window, click the 'x' in the toolbar's window.
