Navigating in the installation wizards
When the installer runs in GUI mode, you navigate using the Next, Previous, Cancel, and Done buttons.
When the installer runs in console mode, you navigate by entering numbers that correspond to the buttons in GUI mode, as described in the help text on each screen of the wizard. In console mode, an additional redisplay command is available.
In console mode, a number or letter is displayed in square brackets at the end of the prompt line; this is the default command issued if you press Enter without typing anything. You can type back to go to a previous screen, or quit to cancel the installation.
