Input mask on a text box field can be used to validate the values as per the format specified. For example if you want the phone number in the US format you may specify the input mask as below :
When this field is filled on the form, user is only allowed to type numbers. Alphabets and special characters are restricted.
Similarly, you may restrict the field to enter only alphabets by using @ and also a combination of alphabets and numbers by using both as shown below.
Hope this information helps.
