CHDK specialities

Due to the camera's keyboard layout, CHDK for the A480 uses the following keys / shortcuts:

) press MODE key shortly for enter/exit <ALT mode>, press MODE key longer for the camera's original function
) press Playback (>) key in CHDK menus as disp/erase button
) press MENU key during video recording for Ev correction

If autostart is used, press the power (on/off) button longer to turn on the camera directly record mode (usual CHDK drawback)

Advanced features

extra long (up to ~2000 seconds) exposures
video features: mute on zoom, AF scan and AE shift (press MENU during video recording to activate AE shift)

For Developers

The Firmware Update method works.
