| "Menus\n" |
| "----------\n" |
| "o Use the Up/Down arrow keys (cursor keys) to highlight the item\n" |
| " you wish to change or submenu wish to select and press <Enter>.\n" |
| " Submenus are designated by \"--->\".\n" |
| "\n" |
| " Shortcut: Press the option's highlighted letter (hotkey).\n" |
| " Pressing a hotkey more than once will sequence\n" |
| " through all visible items which use that hotkey.\n" |
| "\n" |
| " You may also use the <PAGE UP> and <PAGE DOWN> keys to scroll\n" |

| "\n" |
| "o To exit a menu use the cursor keys to highlight the <Exit> button\n" |
| " and press <ENTER>.\n" |
| "\n" |
| " Shortcut: Press <ESC><ESC> or <E> or <X> if there is no hotkey\n" |
| " using those letters. You may press a single <ESC>, but\n" |
| " there is a delayed response which you may find annoying.\n" |
| "\n" |
| " Also, the <TAB> and cursor keys will cycle between <Select>,\n" |
| " <Exit> and <Help>.\n" |

| " and press <ENTER>.\n" |
| "\n" |
| " Shortcut: Press <H> or <?>.\n" |
| "\n" |
| "o To toggle the display of hidden options, press <Z>.\n" |

| "Alternate Configuration Files\n" |
| "-----------------------------\n" |
| "Menuconfig supports the use of alternate configuration files for\n" |
| "those who, for various reasons, find it necessary to switch\n" |
| "between different configurations.\n" |
| "\n" |
| "At the end of the main menu you will find two options. One is\n" |
| "for saving the current configuration to a file of your choosing.\n" |
| "The other option is for loading a previously saved alternate\n" |
| "configuration.\n" |
| "\n" |
| "Even if you don't use alternate configuration files, but you\n" |
| "find during a Menuconfig session that you have completely messed\n" |
| "up your settings, you may use the \"Load Alternate...\" option to\n" |
| "restore your previously saved settings from \".config\" without\n" |
| "restarting Menuconfig.\n" |
| "\n" |
| "Other information\n" |
| "-----------------\n" |
| "If you use Menuconfig in an XTERM window make sure you have your\n" |
| "$TERM variable set to point to a xterm definition which supports color.\n" |
| "Otherwise, Menuconfig will look rather bad. Menuconfig will not\n" |
| "display correctly in a RXVT window because rxvt displays only one\n" |
| "intensity of color, bright.\n" |
| "\n" |
| "Menuconfig will display larger menus on screens or xterms which are\n" |
| "set to display more than the standard 25 row by 80 column geometry.\n" |
| "In order for this to work, the \"stty size\" command must be able to\n" |
| "display the screen's current row and column geometry. I STRONGLY\n" |
| "RECOMMEND that you make sure you do NOT have the shell variables\n" |
| "LINES and COLUMNS exported into your environment. Some distributions\n" |
| "export those variables via /etc/profile. Some ncurses programs can\n" |
| "become confused when those variables (LINES & COLUMNS) don't reflect\n" |
| "the true screen size.\n" |
| "\n" |
| "Optional personality available\n" |
| "------------------------------\n" |
| "If you prefer to have all of the options listed in a single menu, rather\n" |
| "than the default multimenu hierarchy, run the menuconfig with\n" |
| "MENUCONFIG_MODE environment variable set to single_menu. Example:\n" |
| "\n" |
| "make MENUCONFIG_MODE=single_menu menuconfig\n" |
| "\n" |
| "<Enter> will then unroll the appropriate category, or enfold it if it\n" |
| "is already unrolled.\n" |
| "\n" |
| "Note that this mode can eventually be a little more CPU expensive\n" |
| "(especially with a larger number of unrolled categories) than the\n" |
| "default mode.\n" |
| "\n" |
| "Different color themes available\n" |
| "--------------------------------\n" |
| "It is possible to select different color themes using the variable\n" |
| "MENUCONFIG_COLOR. To select a theme use:\n" |
| "\n" |
| "make MENUCONFIG_COLOR=<theme> menuconfig\n" |
| "\n" |
| "Available themes are\n" |
| " mono => selects colors suitable for monochrome displays\n" |
| " blackbg => selects a color scheme with black background\n" |
| " classic => theme with blue background. The classic look\n" |
| " bluetitle => a LCD friendly version of classic. (default)\n" |
