NAME
itemap - load an ITE (Internal Terminal Emulator) keyboard mapping. SYNOPSIS
[options] DESCRIPTION
The command loads a keyboard mapping into the ITE (the graphics console driver), or displays ITE keyboard mappings. is run by automati- cally. It is not usually explicitly invoked by the user. Options Dump a keymap to standard output in hexadecimal notation. Load the specified keymap into the kernel mapping table used for keyboards. Interactively prompt for a keyboard mapping. scans the keymap database file for all mapping names beginning with a prefix. Each of these names is displayed, and one must be selected. The name of the keymap database file to be used for input. The default is Load the appropriate keymap. scans the hardware for a keyboard, determines the language of that keyboard, and loads the keymap corresponding to that keyboard. Because cannot determine the language of keyboards, use the option when using with keyboards. Load a specified keyboard map. Once loaded, ITE uses the specified mapping. When loading a keyboard mapping with the option, matches the suffix of the name of the specified keyboard mapping with those found in to determine the keyboard language. This information is used by the ITE to perform ISO 7-to-8 bit conver- sion. Keymap names added by users, via should use the same suffixes as those already used in For example, a French keyboard mapping can be named for consistency with existing and mappings. A mapping called would not match any suffix patterns found by itemap, and would result in incorrect ISO 7-to-8 bit conversion. Load the specified keymap into the kernel mapping table used for keyboards. Perform actions verbosely. If a keymap for a keyboard is loaded, write its name to file_name. EXAMPLES
