If you wish to find the previous occurence of a string use the question mark instead of the forward slash.
Several characters take on special meaning when used in search strings.
These special characters and their functions are listed in the table at the bottom of this section. The dollar sign used after a string will find the next line that ends with that string. Square brackets surrounding two or more characters will match any single character located between the brackets. Or click here to go to the top of the chapter.
