Here is a list of the most important widgets shown in
seen in Boot Loader Configuration"
Druid":
• Window — Windows (usually referred to as dialogs in this manual) 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 disappears,
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 or deselect a feature.
• Text Input — Text input lines are regions where you can enter information required by the installation
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 program.
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 the cursor
itself may only appear positioned in or next to the widget. In

12.5.1. Using the Keyboard to Navigate

Navigation through the installation dialogs is performed through a simple set of keystrokes. To move
the cursor, use the Left, Right, Up, and Down arrow keys. Use Tab, and Shift-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.
To "press" a button, position the cursor over the button (using Tab, for example) and press Space
or Enter. To select an item from a list of items, move the cursor to the item you wish to select and
press Enter. To select an item with a checkbox, move the cursor to the checkbox and press Space to
select an item. To deselect, press Space a second time.
Pressing F12 accepts the current values and proceeds to the next dialog; it is equivalent to pressing
the OK button.
