The Find and Replace window contains a list of expressions to replace characters or digits in the Find what field. They are called Wildcards.
To select a required wildcard, do the following:
In the Find and Replace dialog, select the Use check box and choose Wildcards from the drop-down list.
The arrow button next to the Find what field becomes active.
The drop-down list contains the following wildcards:
|*||Zero or more of any character||Matches one or more characters. For example, test* matches any text that includes “test”, such as textfile.txt.|
|?||Any single character||Matches any single character.|
|#||Any single digit||Matches any single digit. For example, 5# matches numbers that include 5 followed by another number, such as 51, but not 15.|
|||Any one character in the set||Matches one of the characters specified in the set.|
|[!]||Any one character not in the set||Matches one character that is not specified in the set.|
|\||Escape Special Character||Matches the character that follows the backslash as a literal. This allows you to find the characters used in wildcard notation, such as * and #.|
