! Causes the input mask to start filling in the mask from the right, shifting the characters to the left as you type. Characters typed into the mask normally fill it from left to right. You can include the exclamation point ! (read as "bang") anywhere in the input mask. Useful for fields like telephone numbers where you might not want to enter the area code for the local numbers.
\ Causes the character that follows to be displayed as the literal character (for example, \A is displayed as just A instead of being a place holder for letter). AA\AAA would take typed characters 1234 and display 12A34.
Password Creates a password entry text box. Each character typed is stored but the box displays only asterisks (*). Typing 1234 would display as ****.
