The useSymmetry option is default true. Sorry about the inconsistent bolding, I'll fix it ASAP.
As to why you get a message that the keyword isn't found, could it be that you are using an older version of Chimera? I believe this option was new in Chimera 1.7 (Jan 2013). The latest release is 1.8 (Jun 2013). That would also explain why the behavior is as if the option were set to false.
I hope this helps,
