The accessKey attribute is available for many components like buttons, checkboxes or links.
A component with this attribute is accessible by the given character. The character is not case sensitive.
Logging the accessKey can be configured by setting the category
org.apache.myfaces.tobago.internal.util.AccessKeyLogger to log level "debug".
The usage of accesskeys is different for every OS and browser.
For example, in the Windows-Firefox, you have to press 'Alt + Shift + key'.
In Chrome for Mac OS X it's only 'Control + Alt + key'.
A complete listing can be found at the
Mozilla Developer Network.
