Abstract: Disclosed is a method of browsing a collection of sortable items (201) stored in a digital system. A plurality of grouping hierarchies (207, 217) are provided, each comprising a sort order and zero or more grouping levels (204-206, 214-216) forming groups with which the items are associable. At least one grouping hierarchy comprises a sort order and at least one grouping level. One item (203) in the collection is set to be a focus item (208, 218) thereby establishing a current focus group (209, 219) of a current grouping hierarchy. The focus item is then maintained upon selection of a new grouping hierarchy (210-220) from one of the plurality. A displaying of the collection of items may be performed by arranging the items in a list sorted according to one sort order of a plurality of sort orders associable with the items.

Abstract: A multi user display system having a plurality of individual user terminals and a communal display screen has a server which recovers respective pages for display on the user terminals. The server is also responsive to a command from the user terminals which, when receives, causes the current display on the requesting terminal to be output to the communal display. The server is also responsive to a further command from the user terminals which, when received, causes the current display on the communal browser to become the current display on the requesting terminal.
