Latex font commands are terminated by their enclosing braces. For example, the input 
 
     $latex
     \[
     { abc \bf abc }  abc

Latex Font commands that appear with in an entry in an array are limited to that entry in the array. For example, the input 
 
     $latex
     \[
          \begin{array}{cc}
               \bf \sqrt{x y} & \sqrt{x y } \\
               \sqrt{x y}     & \sqrt{x y }
          \end{array}
     \]
     $$
results in the following output @[@ \begin{array}{cc} \bf \sqrt{x y} & \sqrt{x y } \\ \sqrt{x y} & \sqrt{x y } \end{array} @]@
