Even easier than inserting a rigid space is to position yourself between 
the two t's and hit "*".  This is documented in the manual somewhere, 
but the idea is that if you want to "multiply" two variables then you 
use "*", which inserts a "juxtaposition operator".  (This isn't very 
convenient for multiple-letter variable names, though.  I'd probably 
define a macro for those.)
