Rolodex

As Rolodex (also Rolodex, rotation index ) is an apparatus referred to, in which a plurality of tabs mounted on a rotatable axis. It is used for time-and space-saving Browse in the search for an entry. The device was developed by Arnold Neustadter 1958.

The lookup is facilitated by Reiter, separate the possible equal sections of the sorted index cards. The tabs are labeled for this purpose with the common prefix of a section.

A paperless equivalent is the Taipudex method to look up an entry. This, not a copy of a sought entry in an input field has to be generated as in the mechanical model. The initial index is added into unique steps until the complete entry is reached simultaneously visible or by linking to the associated information. The following steps are obtained in a list or table each single key press. The simple mechanical operation of the Rolodex corresponds to the navigation with the arrow keys on the keyboard. The rotation corresponds to the vertical selection with the Up and Down keys, the unfolding of a rider the horizontal navigation with the key right, the Left button undoes.
