Toolbars

C2A has two tool bars: the main toolbar has shortcuts to the most common commands and the secondary toolbar allows you quick access to predefined zoom levels among other things. The Display Toolbars command in the Tools Menu allows you to turn either tool bar on or off.

Main Toolbar

The main tool bar is divided into several areas. To get information about a button in one of these areas, click on it with the left mouse button.

The Defining the buttons on the main toolbar chapter explains how to change the main tool bar and display only the buttons which are commonly accessed by a given user.

Secondary Toolbar

The secondary toolbar allows you quickly to access a predefined zoom level and to carry out geometrical operations on Field type views. To get information about a button in one of the areas in the secondary toolbar, left click on the button.

These two text areas in this toolbar obey very precise rules:

• When the focus is on a map (that is to say when you have clicked on a map), the regular keyboard shortcuts listed in the help system are available (for example “S” selects a view of the southern horizon). As soon as you hit a numeric key the cursor moves to the field value input box. There you can continue typing a field value, which you validate by hitting ENTER. On pressing the ENTER key the focus moves to the map. Note that when the focus is on the field value input box, keyboard shortcuts (e.g. S, W, E, N...) become inoperative; this is normal. This system allows you to type several successive field values without having to use the mouse, which is convenient. For example, 20 followed by ENTER then 30 followed by ENTER etc... allows you to successively display 20°, 30°, etc... fields.

• To use the field rotation input box (only available in views of the Field type) you must click the box with the mouse, or shift focus to the box by hitting the Tab key (as in typical Windows applications). There, you enter a valid rotation value and input it by hitting Enter (this value can be decimal). Using the Enter key leaves the value just entered in the box highlighted, so that a new value can be quickly entered without having to erase the previous one. In this way you can enter a series of values approaching bit by bit the rotation you are aiming for. To a field rotation, just type 0 and Enter.

• These two input boxes are shortcuts because there are other ways of achieving the same result (using the field definition zone in the control panel to enter the field value, and through the options dialogue box to input the field rotation).

• For both input boxes, hitting Esc clears the box and transfers focus to the map.
