[PATCH] Right-click modifier
Hi,
this patch adds an entry in /proc,
/proc/sys/dev/mac_hid/rclick_key_modifier.
It lets the kernel report a right-click when KEY+Left click are pressed,
where KEY is the KEY specified by echoing its code to the /proc entry.
ie, "echo 29 > /proc/sys/dev/mac_hid/rclick_key_modifier" and you'll have
Ctrl-click = right click.
It's a patch against linuxppc-2.5-benh tree rsync'ed tonight from
source.mvista.com.
hope it's useful,
