problems with zoom and zoom_speed

Hi!

I've got S5 IS.
I write a script that starts recording video. I want to add possibility to change zoom during recording:

z=z+i
if z>128 then z=128
press "zoom_in"
do
   get_zoom y
until y>=z
release "zoom_in"

In movie mode there are avaliable two speeds of zooming. Press "zoom_in" function is zooming in with high speed, like when i turn zooming thing on the camera full right.  How to zoom with lower speed (like turning halfway)? Set_zoom_speed does not work. Is there something like press "zoom_in_half" ?
Any ideas? :-[

If I'm not mistaken, that hasn't been implemented in CHDK. Then again the way I see it in s5 kbd.c, I would've guessed it would always zoom slowly... :blink:

Anyway, you might be able to find an event that sends this particular keypress or one that causes slow zoom. Events are available through a Lua interface but it probably requires some work to find (and test) the events. See http://chdk.wikia.com/wiki/LogicalEvent .
