{only available when compiled with the |+langmap| feature} This option allows switching your keyboard into a special language mode. When you are typing text in Insert mode the characters are inserted directly. When in Normal mode the 'langmap' option takes care of translating these special characters to the original meaning of the key. This means you don't have to change the keyboard mode to be able to execute Normal mode commands. This is the opposite of the 'keymap' option, where characters are mapped in Insert mode. Also consider setting 'langremap' to off, to prevent 'langmap' from applying to characters resulting from a mapping. This option cannot be set from a |modeline| or in the |sandbox|, for security reasons.
