Subject: HID: appletb-kbd: add option to switch default layer on double
|
|
pressing fn key
|
|
|
|
This patch enables a user to switch the default layer from media to fn
|
|
keys and vice-versa upon double pressing the fn key. This behaviour can
|
|
be configured using the double_press_switch_time module parameter whose
|
|
value depicts the time in milliseconds within which the fn key must be
|
|
pressed again to switch the default layer. If set to 0, it simply
|
|
disables this behaviour.
