(:Summary: Customisable browser setting preferences: Access keys, edit form:)
The page [[{$SiteGroup}.Preferences]] contains customisable browser preference settings.
These include [[access keys]] (keyboard shortcuts to certain actions like edit, history, browse) and settings of the [[{$SiteGroup}.EditForm]] (width and height of the edit textarea) as well as the name of the edit form in use.

A different page than [[{$SiteGroup}.Preferences]] can be chosen by making a copy of that page under a new name, customising it, and setting a cookie which will point to this page for the browser being used, through 

   ?setprefs=`SomeGroup.`CustomPreferences 

`SomeGroup.`CustomPreferences being the name of the new customised preference page.

!!Notes and Comments

Note that in order to enable parsing of [[{$SiteGroup}.Preferences]] by default, a line like the following needs to be added to local/config.php:

 XLPage('prefs', "Site.Preferences");
