<p>Clicking the "Replace" link in the Toolbar will display a form at the top of the page allowing you to search within files for a specific string of text and replace it with a new string of text.  Simply check the box of the file you wish to perform the replace function on, enter the string you wish to replace, enter the string you wish to replace it with, and click replace.</p>
<ul>
  <li>The "Replace" drop-down menu allows you to choose whether you wish to search the entire directory you are viewing for the string you wish to replace, or only selected files and subdirectories within that directory (select these files and directories by clicking the checkboxes beside them in the Files menu).  Note that directories "above" the one you are viewing cannot be searched for strings to replace; searching a directory named "images" in the root directory will not search any of the other directories and files in the root directory.</li>
  <li>Choose whether or not your search for strings will be "case sensitive" using the checkbox provided.</li>
  <li>Choose whether or not you wish to search using a regular expression with the "Regular Expression" checkbox provided. This allows users with some knowledge of regular expressions to search for files with content meeting specified criteria. Clicking the "Regular Expression" checkbox will automatically check the "Search Contents" box.</li>
  <li>If you choose to "Create .bak," a backup file containing the original string of text will be created in the same directory as any files that were modified by the replacement.  If, for example, you had a file named "colour.txt" containing the word "blue", and you used the replace option to substitute "blue" with "red" with the "Create .bak file" option enabled, two files would now appear in the directory that "colour.txt" is located in: a "colour.txt" file containing the word "red", and a "colour.txt.bk" file containing the word "blue".</li>
</ul>
