I'm not too familiar with graphics handles. Hopefully this is a quick question.
Is it to simplify checks when setting or getting defaults, e.g. for set(0,'blah','blah')?

Hi,
yes 0 is the handle to the default settings/properties and because of this ishandle(0) returns 1.

Thanks for the quick response. I hope this question helps people who run into the same thing. I really think that this should be added to the ishandle documentation.

0 is the numeric handle to the root object. You can find a list of its properties here.
