Shutter release control

If I'm using my camera (IXUS  970IS) manually I can press the shutter button half way, then repeatedly press and half release the shutter button. This lets me take a rapid series of pictures without having to re-focus or re-meter

Anyone know how I can write a script to do the same. The initial half press is no problem - press "shoot_half" does the trick. Pressing the shutter fully is also easy - press "shoot_full". But then I'm stuck - how do I get back to the half pressed shutter? - release "shoot_full" is no good as that releases the shutter completely.

Any ideas much appreciated.

Thanks,
Alan

PS Problem I'm actually trying to solve is how to speed up this script (which works but has a far lower shooting rate than manually pressing the shutter button)

    wait_click 1
    if is_key "remote" then shoot
wend

Are you saving using the same format / size when shooting with your script than when shooting manually ?
