Figure 3 2. Installation Program Widgets as seen in Disk Druid

Here is a list of the most important widgets shown in Figure 3 1, and Figure 3 2:

Window   windows (usually referred to as dialogs in this manual) will appear on your screen

throughout the installation process. At times, one window may overlay another; in these cases, you

can only interact with the window on top. When you are finished in that window, it will disappear,

allowing you to continue working in the window underneath.

Checkbox   checkboxes allow you to select or deselect a feature. The box displays either an

asterisk (selected) or a space (unselected). When the cursor is within a checkbox, press [Space] to

select an unselected feature or to deselect a selected feature.

Text Input   text input lines are regions where you can enter information required by the installa 

tion program. When the cursor rests on a text input line, you may enter and/or edit information on

that line.

Text widget   text widgets are regions of the screen for the display of text. At times, text widgets

may also contain other widgets, such as checkboxes. If a text widget contains more information

than can be displayed in the space reserved for it, a scroll bar appears; if you position the cursor

within the text widget, you can then use the [Up] and [Down] arrow keys to scroll through all

the information available. Your current position is shown on the scroll bar by a # character, which

moves up and down the scroll bar as you scroll.

Scroll Bar   scroll bars appear on the side or bottom of a window to control which part of a list or

document is currently in the window's frame. The scroll bar makes it easy to move to any part of a

file.

Button widget   button widgets are the primary method of interacting with the installation pro 

gram. You progress through the windows of the installation program by navigating these buttons,

using the [Tab] and [Enter] keys. Buttons can be selected when they are highlighted.

Cursor   although not a widget, the cursor is used to select (and interact) with a particular widget.

As the cursor is moved from widget to widget, it may cause the widget to change color, or you may

only see the cursor itself positioned in or next to the widget. In Figure 3 1, the cursor is positioned

on the OK button. Figure 3 2, shows the cursor on the Edit button.

3.2.1. Using the Keyboard to Navigate

Navigation through the installation dialogs is performed through a simple set of keystrokes. To move

the cursor, use [Left], [Right], [Up], and [Down] arrow keys. Use [Tab], and [Alt] [Tab] to cycle

forward or backward through each widget on the screen. Along the bottom, most screens display a

summary of available cursor positioning keys.
