Not every entry in the table is valid for all CHDK-supported cameras. You
should check specific property cases for your camera before using them.
You can do this with the help of the script propdump.lua, which you will
find on the book CD. Execute the script once (section 5.1) to create a first
Property Dump. Then modify the camera setting and execute the script a
second time. By setting parameter I, you can compare the second property
dump with the first one. The differences between them will be displayed
on the screen and give you a hint as to which property relates to the
changed camera setting.
