*template-chars*

The value of this variable is an association list describing how various characters in a template-string are to be interpreted. The initial value of this list is:

((#\space graphic-char-p #\space) 
 (#\c alphanumericp #\space) 
 (#\a alpha-char-p #\space) 
 (#\9 digit-char-p #\space))

Each entry consists of

(1) a template-character,

(2) a predicate function that determines which characters may be typed by the user at positions where that template character is specified (this predicate should take one argument, which should be a character, and return non-nil if the character passed to it is allowed), and

(3) a character to initially display in the control at the positions of that template character (these are all #\space by default).
