for Emacs, I want to use CTRL key in android

[kty1104]

hello
I need some help
because of Emacs,
I run the ubuntu in froyo(android 2.2)
and connect with android vnc viewer

but in android vnc viewer, it is hard to use
ctrl, alt, left mouse, right mouse button
so I make several experiment.
modify /system/usr/keylayout/eve_qwerty.kl (since my phone is gw620-eve)
but I can't remap the volume button to CTRL key
though I can remap the volume button to ALT key
key 114 VOLUME_DOWN WAKE -> key 114 ALT_LEFT

I also tried changing eve_qwerty.kcm.bin file as well


is there any special name for CTRL as like ALT_LEFT? I can't remap with CTRL_LEFT or CONTROL?
could somebody let me know ASCII code of CTRL?
or could somebody let me know how to apply this(http://developer.android.com/reference/android/view/KeyEvent.html)
useful reference to my work?
I need a help
you little advice would be very helpful for me
non-solution is fine please just give me an little hint
