Appeal No. 94-1490
Application 08/135,833
The invention relates to a telecommunication device
(e.g., a facsimile unit) including a display panel and a keyboard
having an Undo key. In addition to the normal function of
canceling the immediately previous keyboard instruction, the
claimed Undo key performs the following functions: (a) when the
effect of one or more immediately prior actions was to shift the
cursor to a character position other than the last displayed
character position, a single operation of the Undo key causes the
cursor to move to the last displayed character position; and
(b) a subsequent operation of the Undo key with the cursor in the
last displayed character position causes that character to be
deleted and the cursor to move back one position.
Apparatus claim 1 reads as follows:
1. A telecommunication unit including an operator
panel with a keyboard and a display panel, said
operator panel including a key designated Undo, said
telecommunication unit comprising:
processor means responsive to a user actuation of
said key designated Undo, to reverse at least an
immediately previous user-commanded action and to cause
said telecommunication unit to manifest a state in
existence just prior to said immediately previous
operator-commanded action, and if said immediately
previous user-commanded action results in a displayed
cursor on said display panel being located at any
character position within a name or number field which
is other than a last displayed character in said name
or number field, said processor means responds to
actuation of said key designated Undo by moving said
