"Some OpenWrt features may be built directly into the image.\n"
"Some may be made into installable ipkg packages. Some features\n"
"may be completely removed altogether.\n"
"\n"
"Menu items beginning with [*], <M> or [ ] represent features\n"
"configured to be included, built as package or removed respectively.\n"
"Pointed brackets <> represent packaging capable features.\n"
"\n"
"To change any of these features, highlight it with the cursor\n"
"keys and press <Y> to include it, <M> to make it a package or\n"
"<N> to remove it. You may also press the <Space Bar> to cycle\n"
"through the available options (ie. 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\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"
" 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> and <Help>\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"
"\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"

" 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"

"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 OpenWrt 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 build options listed in a single\n"
"menu, rather than the default multimenu hierarchy, run the menuconfig\n"
"with 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"
