Navigates to a lookup page.
Returns a Promise object or the 'this' object.
The required page is the name of the lookup page being navigated to.
Options is a struct that can have the following items, all of which are optional.
Mode is a string that determines the whether the lookup value is copied in edit mode (as a manipulation) or in search mode (as a search value). The default is 'edit'.
Page-target is a string specifying whether the lookup page must be displayed in Dialogs mode or in Pages mode. In Dialogs mode, the lookup page appears as a modal dialog. In Pages mode, the current page is replaced by the lookup page. The value 'Dialogs' (the default) denotes Dialogs mode. 'Pages' denotes Pages mode. 'Current' denotes the mode of the current page context, which is either Dialogs mode or Pages mode.
Title has an effect only if page-target is set to 'Dialogs'. Title is a string representing the lookup dialog title to be used.
Quiet is a boolean that determines whether or not a message is displayed if an error occurs. Default is false, meaning that a message is displayed by default.
Promise determines the return value of this function. If promise has the value 'true' (the default), a Promise object is returned. If promise has the value 'false', the ‘this’ object is returned instead.
Success-function is a function called after the operation has successfully completed.
Error-function is a function called if an error occurs.
