Claim 5

A method according to claim 1 , wherein the subset of the sequence of changes comprise changes associated with a cursor location in the document.

Claim 6

A method according to claim 1 , wherein the subset of the sequence of changes comprise all of the sequence of changes.

Claim 7

A method according to claim 1 , wherein the subset of the sequence of changes comprise changes having a common undo type.

Claim 8

A method according to claim 6 , wherein the undo types are selected from the group comprising insertion changes, deletion changes and change changes.

Claim 9

A method according to claim 6 , wherein the step of obtaining user input so as to selects a subset of the sequence of changes to the text of the document comprises the steps of: obtaining user input as to a common undo type; and selecting all of the changes in the sequence of changes having the common undo type.

Claim 10

A programmed computer system to enable a user to edit a document containing initial text stored in and displayed by said computer system, comprising: means for a user to enter into the computer system a plurality of changes to the initial text of the document so as to provide a sequence of changes; means for selecting a subset of the sequence of changes; means for displaying the document with the subset of the sequence of changes; means for selecting and undoing changes in the subset of the sequence of changes irrespective of the sequence in which the changes to the initial text of the document were made; means for implementing changes in the sequence of changes which are not selected and undone so as to provide an edited document; and means for displaying and storing the edited document and the selected changes undone so that the stored document includes text corresponding to the undone changes along with the remaining plurality of changes.

Claim 11

A programmed computer system to enable a user to edit a document containing initial text stored in and displayed by said computer system, comprising: means for a user to enter into the computer system a plurality of changes to the initial text of the document so as to provide a sequence of changes; means for selecting a subset of the sequence of changes; means for displaying the document with the subset of the sequence of changes; means for selecting and undoing changes in the subset of the sequence of changes irrespective of the sequence in which the changes to the initial text of the document were made; means for implementing changes in the sequence of changes which are not selected and undone so as to provide an edited document; and means for displaying and storing the edited document and the selected changes undone so that the stored document includes text corresponding to the undone changes along with the remaining plurality of changes.

Claim 12

A system according to claim 5 , wherein the subset of the sequence of changes comprise changes from a generation of changes.

Claim 13

A system according to claim 5 , wherein the subset of the sequence of changes comprise changes associated with a cursor location in the document.

Claim 14

A system according to claim 5 , wherein the subset of the sequence of changes comprise changes having a common undo type.

Claim 15

A method according to claim 12 , wherein the undo types are selected from the groups comprising insertion changes, deletion changes and change changes.

Claim 16

A method according to claim 12 , wherein the means for selecting a subset of the sequence of changes comprises: means for obtaining user input as to a common undo type; and means for selecting all of the changes in the sequence of changes having the common undo type.

Claim 17

A computer program product comprising: a computer usable medium having computer readable program code means embodied therein for causing the editing of a document containing initial text, the computer readable program code means in said computer program product comprising: computer readable program code means for causing a computer to enter a plurality of changes to the initial text of the document so as to provide a sequence of changes to the document; computer readable program code means for selecting a subset of the sequence of changes; computer readable program code means for causing the document to be displayed on a monitor with the subset of the sequence of changes; computer readable program code means, in response to user inputs, for selecting and undoing changes in the subset of the sequence of changes displayed on the monitor irrespective of the sequence in which the changes to the initial text of the document were made; computer readable program code means for implementing changes in the sequence of changes which are not selected and undone so as to provide an edited document; and computer readable program code means for displaying and storing the edited document and the selected changes undone so that the stored document has text corresponding to the undone changes along with the remaining plurality of changes.

Claim 18

A computer program product comprising: a computer usable medium having computer readable program code means embodied therein for causing the editing of a document containing initial text, the computer readable program code means in said computer program product comprising: computer readable program code means for causing a computer to enter a plurality of changes to the initial text of the document so as to provide a sequence of changes to the document; computer readable program code means for selecting a subset of the sequence of changes; computer readable program code means for causing the document to be displayed on a monitor with the subset of the sequence of changes; computer readable program code means, in response to user inputs, for selecting and undoing changes in the subset of the sequence of changes displayed on the monitor irrespective of the sequence in which the changes to the initial text of the document were made; computer readable program code means for implementing changes in the sequence of changes which are not selected and undone so as to provide an edited document; and computer readable program code means for displaying and storing the edited document and the selected changes undone so that the stored document has text corresponding to the undone changes along with the remaining plurality of changes.

Claim 19
