+Four different entries are displayed below.  You can add characters \
+by pointing, clicking and typing, though each is constrained in what \
+it will accept.  The first only accepts integers or the empty string \
+(checking when focus leaves it) and will flash to indicate any \
+problem.  The second only accepts strings with fewer than ten \
+characters and sounds the bell when an attempt to go over the limit \
+is made.  The third accepts US phone numbers, mapping letters to \
+their digit equivalent and sounding the bell on encountering an \
+illegal character or if trying to type over a character that is not \
+a digit.  The fourth is a password field that accepts up to eight \
+characters (silently ignoring further ones), and displaying them as \
+asterisk characters.
