| "This interface lets you select features and parameters for the build.\n" |
| "Features can either be built-in, modularized, or ignored. Parameters\n" |
| "must be entered in as decimal or hexadecimal numbers or text.\n" |
| "\n" |
| "Menu items beginning with following braces represent features that\n" |
| " [ ] can be built in or removed\n" |
| " < > can be built in, modularized or removed\n" |
| " { } can be built in or modularized (selected by other feature)\n" |
| " - - are selected by other feature,\n" |
| "while *, M or whitespace inside braces means to build in, build as\n" |
| "a module or to exclude the feature respectively.\n" |
| "\n" |
| "To change any of these features, highlight it with the cursor\n" |
| "keys and press <Y> to build it in, <M> to make it a module or\n" |
| "<N> to remove it. You may also press the <Space Bar> to cycle\n" |
| "through the available options (i.e. Y->N->M->Y).\n" |
| "\n" |
| "Some additional keyboard hints:\n" |
| "\n" |
| "Menus\n" |
| "----------\n" |
| "o Use the Up/Down arrow keys (cursor keys) to highlight the item you\n" |
| " wish to change or the submenu you wish to select and press <Enter>.\n" |
| " Submenus are designated by \"--->\", empty ones 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" |
| " unseen options into view.\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>, <Help>, <Save>, and <Load>.\n" |
| "\n" |
| "o To get help with an item, use the cursor keys to highlight <Help>\n" |
| " and press <ENTER>.\n" |
| "\n" |
| " Shortcut: Press <H> or <?>.\n" |
| "\n" |
| "o To toggle the display of hidden options, press <Z>.\n" |
| "\n" |
| "\n" |
| "Radiolists (Choice lists)\n" |
| "-----------\n" |
| "o Use the cursor keys to select the option you wish to set and press\n" |
| " <S> or the <SPACE BAR>.\n" |
| "\n" |
| " Shortcut: Press the first letter of the option you wish to set then\n" |
| " press <S> or <SPACE BAR>.\n" |
| "\n" |
| "o To see available help for the item, use the cursor keys to highlight\n" |
| " <Help> and Press <ENTER>.\n" |
| "\n" |
| " Shortcut: Press <H> or <?>.\n" |
| "\n" |
| " Also, the <TAB> and cursor keys will cycle between <Select> and\n" |
| " <Help>\n" |
| "\n" |
| "\n" |
| "Data Entry\n" |
| "-----------\n" |
| "o Enter the requested information and press <ENTER>\n" |
| " If you are entering hexadecimal values, it is not necessary to\n" |
| " add the '0x' prefix to the entry.\n" |
| "\n" |
| "o For help, use the <TAB> or cursor keys to highlight the help option\n" |
| " and press <ENTER>. You can try <TAB><H> as well.\n" |
| "\n" |
| "\n" |
| "Text Box (Help Window)\n" |
| "--------\n" |
| "o Use the cursor keys to scroll up/down/left/right. The VI editor\n" |
| " keys h,j,k,l function here as do <u>, <d>, <SPACE BAR> and <B> for\n" |
| " those who are familiar with less and lynx.\n" |
| "\n" |
| "o Press <E>, <X>, <q>, <Enter> or <Esc><Esc> to exit.\n" |
| "\n" |
| "\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" |
| "The <Save> button will let you save the current configuration to\n" |
| "a file of your choosing. Use the <Load> button to load a previously\n" |
| "saved alternate configuration.\n" |
| "\n" |
| "Even if you don't use alternate configuration files, but you find\n" |
| "during a Menuconfig session that you have completely messed up your\n" |
| "settings, you may use the <Load> button to restore your previously\n" |
| "saved settings from \".config\" without 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 an xterm definition which supports\n" |
| "color. Otherwise, Menuconfig will look rather bad. Menuconfig will\n" |
| "not display correctly in an 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,\n" |
| "rather 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" |
| |
| "Search\n" |
| "-------\n" |
| "Pressing the forward-slash (/) anywhere brings up a search dialog box.\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 => an LCD friendly version of classic. (default)\n" |
