The syntax was changed since that time -- if you use command "help sym" it will show the sym command documentation that goes with your downloaded version. Or, the development (current daily build) docs can be viewed here:
It used to be that "t" was used for translation, but when tetrahedral symmetry was added in July, "t" was used for tetrahedral symmetry instead and "shift" was used for translation. Thus f you were intending to use translational symmetry, it should work to replace the "t" in what you tried with "shift".
In general it is better to use the Help menu before searching for posts, as the information online might be for a different version of Chimera than you are using.
I hope this helps,
