 * A check box to activate Regex. This is a special function to apply a more flexible auto-coding based in wildcards and other functions. See [https://techearl.com/regex-cheat-sheet](https://techearl.com/regex-cheat-sheet)
 
 Automatic coding is case sensitive. You must also define the end of a sentence, there is a default setting with a period and space. \n can be used also to denote a line ending character.

 For auto-coding exact text matches, multiple sections of text can be assigned by auto code using the pipe ‘|’ symbol. For example, politics|politicians can be assigned to the same code at the same time (for exact auto code text matches only). There is an undo option to undo recently performed auto-coding. Although if the project is closed and reopened, the undo option will be lost.
 
-The _Auto-code exact text_ button has a right-click menu for more options. The default is to auto-code all text. There are options to autocode only the first matching text or the last matching text in the document. The auto-code exact text asks which files you want auto-coded, so this is a useful option of you want to identify only one instance across many files.

A menu option allows you to get the first approximately 50,000 characters, subsequent clicks will open the next approximately 50,000 and so on. Approximately, because QualCoder looks for a line-ending (such as a paragraph or sentence ending) to more nicely section the start and end of text chunks.
