DESCRIPTION

The utility allows you to read and check various parameters of the keyboard and virtual console.

getmode: Get or check virtual console mode.
gkbmode: Gets current keyboard mode.

raw: Raw (scancode) mode. These are the raw codes generated by the keyboard.
mediumraw: Medium raw (scancode) mode. This is extended medium raw mode, with keys above 127 encoded as 0, high 7 bits, low 7 bits, with the 0 bearing the 'up' flag if needed. 0 is reserved, so this shouldn't interfere with anything else. The two bytes after 0 will always have the up flag set not to interfere with older applications. This allows for 16384 different keycodes, which should be enough.
xlate: Translate keycodes using keymap. These are the codes generated via the current keysym mapping.
unicode: Unicode mode.

gkbmeta: Gets meta key handling mode.

escprefix: Specifies if pressing the meta (alt) key generates an ESC (\033) prefix followed by the keysym.
metabit: The keysym marked with the high bit set.

gkbled: Get keyboard flags CapsLock, NumLock, ScrollLock (not lights).

scrolllock: The scroll lock is down.
numlock: The num lock is down.
capslock: The caps lock is down.
