hidden
Description: Store data in a hidden form field.
Properties: #prefix, #suffix, #type, #value
#default_value is also a property. If you want to allow javascript to modify a hidden field's value, then you have to use #default_value to set the starting value when drawing the form. If you use #value, then javascript changes to the value will not be available in the form's _submit() function.
#1
It's my understanding that giving a field type like hidden or value a #default_value is Very Very Dangerous (tm). I'll check with chx or eaton, but afaik this is a practice greatly discouraged. I'm not sure what the workaround is, however.
#2
Changed the component to reflect the new component categorization. See http://drupal.org/node/301443
