526 If your computer has a keyboard designed for a language like Russian or
527 Greek, where you have to go to some trouble to type Roman-alphabet
528 characters, then typing @kbd{C-f} to call @code{forward-character} is
529 very inconvenient.
530
531 To address this, XEmacs allows you to pretend that your keyboard has a
532 US layout for such commands. That is, you can type @kbd{C-Cyrillic_che
533 C-Cyrillic_a} and XEmacs will work out that it should call the command
534 that @kbd{C-x C-f} is bound to@footnote{You can, of course, override
535 this with an explicit binding for @kbd{C-Cyrillic_che C-Cyrillic_a} to
536 something else.}. Function keys, like @key{F1},
537 @key{Shift} or @key{Control} are not handled by this, just alphanumeric
538 characters and punctuation.
539
540 The main user variable associated with this functionality is
541 @code{try-alternate-layouts-for-commands}. Setting this to @code{nil}
542 inhibits this translation, which would be appropriate if your keyboard
543 can handle the Roman alphabet but doesn't have the US layout, and you
544 want to avoid the possible confusion.
545
546 If @code{try-alternate-layouts-for-commands} is @code{t} but this
547 functionality doesn't work for you under X11, check the value of the
548 variable @code{x-us-keymap-description}. This is a hardware-specific
549 map from key codes to the US layout, and can be initialized from the
550 output of @code{xmodmap -pke}; see the documentation for that variable
551 and for @code{x-us-keymap-first-keycode}.
