This setting controls the pattern Genie uses to detect "special" function key labels on screen when creating links/buttons for function keys. Special keys include Enter, Page Up/Down, Help and Print. For normal function keys (the F1-F12 keys) see Function Key Pattern.
This setting causes Genie to search each field on the screen for a matching pattern. If your key label spans multiple fields, use the Special Key Pattern2 feature instead.
The default pattern locates the words Enter, PageUp, PageDown, etc, followed by a separator (equal sign or dash), followed by the text. The parenthesis shown are used to "capture" the different parts (key name, separator and text) so that the appropriate words can be placed on the resulting buttons or links that Genie places on the screen.
By defining a different pattern in your custom.js file, you can change the strings and separators that Genie searches for.
The alternate syntax is available after Profound UI V6 FP2.0. It permits you to set the pattern to a RegExp object, allowing you to avoid confusion escaping certain characters, such as the backslash (\).
