These are not "accessories". They are variables whose data determine how various objects look and behave.

Uhmm... are you sure Xray?

Yes! I've been hanging around Algobox since 2012 and I was active in the Algodoo forum back then when people were using it, and I've never heard those things referred to as "Accessories". I guess you can call them anything you want to call them, but the most common thing to call them is "Variables". Some things are called "Commands" if they do not have a changeable value (variable) associated with them.

If you need confirmation, go to the Algodoo forum (the link is at the top of any Algobox page) and scroll down to "Thyme Scripting". In Thyme Scripting the very first entry is called "Commands and Variables List". That entry explains what all of those things are used for.
