This driver provides the wscons(4)
driver with support for Apple Desktop Bus keyboards.
options ALTXBUTTONS
- To map ⟨Option⟩+⟨1⟩,
⟨Option⟩+⟨2⟩,
⟨Option⟩+⟨3⟩, to mouse buttons 1, 2, and 3
respectively.
options CAPS_IS_CONTROL
- On macppc systems it is possible to tweak the keyboard driver to treat the
caps lock key on an ADB keyboard as a control key. This requires special
remapping because of ADB's strange emulation of a mechanically-locked
key.
options FORCE_FUNCTION_KEYS
- On macppc PowerBooks, several function keys double as “hot
keys” (brightness, volume, eject) when the ⟨Fn⟩
modifier is held down. Mac OS X likes to reprogram the keyboard
controller to send hot key events when ⟨Fn⟩ is
not held down and send function key events when it is.
With this option you can transform the non-keyboard “button”
events back into function key events.
To work around the limited number of buttons found on most ADB mice, the
following key sequences trigger mouse button events:
- ⟨Option⟩+⟨LeftArrow⟩ will work as the middle
mouse button.
- ⟨Option⟩+⟨RightArrow⟩ will work as the right
mouse button.
On PowerBook (mac68k) models the following key sequences are also
significant:
- ⟨Option⟩+⟨UpArrow⟩ increase screen
brightness.
- ⟨Option⟩+⟨DownArrow⟩ decrease screen
brightness.
NetBSD is known to support the following ADB keyboards:
- On-board keyboards on PowerBook models
- Apple Standard Keyboard
- Apple Keyboard II
- Apple Extended Keyboard
- Apple Extended Keyboard II
- Apple Adjustable Keyboard
- Most third-party ADB keyboards are supported
The number pad on extended keyboards does not send out the proper key codes for
many applications.
The LEDs on extended keyboards are not functional under
NetBSD.
In X11 with the default key mapping, middle and right mouse button
events will hold ‘Meta_L
’ and this
will clobber the intended mouse button. ⟨Option⟩ shoud be
remapped with xmodmap(1) to
the ⟨Command⟩ key:
remove Mod4 = Super_L
remove Mod1 = Alt_L
add Mod1 = Super_L
