30 | "--------\n" |
31 | "Some kernel features may be built directly into the kernel.\n" |
32 | "Some may be made into loadable runtime modules. Some features\n" |
33 | "may be completely removed altogether. There are also certain\n" |
34 | "kernel parameters which are not really features, but must be\n" |
35 | "entered in as decimal or hexadecimal numbers or possibly text.\n" |
36 | "\n" |
37 | "Menu items beginning with [*], <M> or [ ] represent features\n" |
38 | "configured to be built in, modularized or removed respectively.\n" |
39 | "Pointed brackets <> represent module capable features.\n" |
40 | "\n" |
41 | "To change any of these features, highlight it with the cursor\n" |
42 | "keys and press <Y> to build it in, <M> to make it a module or\n" |
43 | "<N> to removed it. You may also press the <Space Bar> to cycle\n" |
44 | "through the available options (ie. Y->N->M->Y).\n" |

46 | "Some additional keyboard hints:\n" |

50 | "o Use the Up/Down arrow keys (cursor keys) to highlight the item\n" |
51 | " you wish to change or submenu wish to select and press <Enter>.\n" |
52 | " Submenus are designated by \"--->\".\n" |
53 | "\n" |

57 | "\n" |
58 | " You may also use the <PAGE UP> and <PAGE DOWN> keys to scroll\n" |
59 | " unseen options into view.\n" |
60 | "\n" |
61 | "o To exit a menu use the cursor keys to highlight the <Exit> button\n" |
62 | " and press <ENTER>.\n" |
63 | "\n" |
64 | " Shortcut: Press <ESC><ESC> or <E> or <X> if there is no hotkey\n" |

99 | "\n" |

113 | "Alternate Configuration Files\n" |
114 | "-----------------------------\n" |
115 | "Menuconfig supports the use of alternate configuration files for\n" |
116 | "those who, for various reasons, find it necessary to switch\n" |
117 | "between different kernel configurations.\n" |
118 | "\n" |
119 | "At the end of the main menu you will find two options. One is\n" |
120 | "for saving the current configuration to a file of your choosing.\n" |
121 | "The other option is for loading a previously saved alternate\n" |
122 | "configuration.\n" |
123 | "\n" |
124 | "Even if you don't use alternate configuration files, but you\n" |
125 | "find during a Menuconfig session that you have completely messed\n" |
126 | "up your settings, you may use the \"Load Alternate...\" option to\n" |
127 | "restore your previously saved settings from \".config\" without\n" |
128 | "restarting Menuconfig.\n" |
129 | "\n" |
130 | "Other information\n" |
131 | "-----------------\n" |
132 | "If you use Menuconfig in an XTERM window make sure you have your\n" |
133 | "$TERM variable set to point to a xterm definition which supports color.\n" |
134 | "Otherwise, Menuconfig will look rather bad. Menuconfig will not\n" |
135 | "display correctly in a RXVT window because rxvt displays only one\n" |
136 | "intensity of color, bright.\n" |
137 | "\n" |
138 | "Menuconfig will display larger menus on screens or xterms which are\n" |
139 | "set to display more than the standard 25 row by 80 column geometry.\n" |
140 | "In order for this to work, the \"stty size\" command must be able to\n" |
141 | "display the screen's current row and column geometry. I STRONGLY\n" |
142 | "RECOMMEND that you make sure you do NOT have the shell variables\n" |
143 | "LINES and COLUMNS exported into your environment. Some distributions\n" |
144 | "export those variables via /etc/profile. Some ncurses programs can\n" |
145 | "become confused when those variables (LINES & COLUMNS) don't reflect\n" |
146 | "the true screen size.\n" |

149 | "------------------------------\n" |
