3.2. Guidelines Settings
Guidelines settings allow you to select the checkpoints that will be checked during the page analysis.
At the top of the window there are four options.
- The first three options A, AA, AAA, are associated to the three levels of analysis that correspond to the accessibility levels A, double-A and triple-A, established by WAI.
- The fourth option, Customized, allows to select, individually, the checkpoints to be checked during the analysis.
The checkpoints are grouped by priority level within different tabs, one tab for each priority level and one additional tab that will contain checks created by the user. In each tab, there is a number that by right clicking will allow to select or deselect all the checkpoints of the priority level displayed.
Once a customized setting is created, it can be saved in a file and recovered later, allowing to have a predefine repository of analysis.
Access to the guidelines settings through the Guidelines menu, or through the analyser 
Guidelines button.
User Checks
As well as the Web Content Accessibility Guidelines 1.0 (WCAG 1.0), it is possible to define customized checks to complement the guidelines. An user check or a customized check is a search string (regular expression) that is applied to one or more HTML labels.
- To create an user check, click the New button.
- Next, you have to select the label or labels you want to add (to perform a multiple selection, hold down the CRTL button).
- Then, select the type of check: automatic or human review. Introduce the searching Regular expression, or click the Wizard button to create automatically a regular expression based on predefined parameters.
- Introduce at the Short description text box, a brief comment of the problem. At the Help message text box you can explain the cause of the problem and how to resolve it.
- Lastly, click the Apply or the OK button to save the changes. In the first option, the check window will remain opened, and in the second option, once the changes are saved, the window will close. To delete the changes, click the Cancel button.
To eliminate a check, select the check to be deleted from the Checks pull-down menu, and click the Delete button.
To modify a user check, select the check to be modified in the Checks pull-down menu. Once the check is selected, introduce the new values. To save these changes, click the OK button or the Apply button. If you wish to cancel the changes, click the Cancel button.
Creation of a regular expression with the wizard
The wizard allows you to create basic regular expressions based on the following data:
- Check whether there is or not a particular attribute. With the first option, Required, an accessibility issue will occur if the attribute indicated does not exist in the labels selected previously. In the second option, Not allowed, an accessibility issue will be detected if the attribute exists.
- Next, write the attribute name in the Attribute text box.
- If a specific value is required for the attribute, active Search pair, and indicate the required value in the Value text box.
- Once, all this information is introduced, click the OK button to generate the regular expression, or the Cancel button, to return to the user check window without generating the regular expression.
