Abstract

Determining and applying format attributes associated with content in an electronic document that is cut or copied from an electronic document and pasted into the same or different electronic document. The determination may be based on the format attributes of the content within a region of an electronic document containing the cut or copied content and the format attributes of a region of content that includes the location where the cut or copied text may be pasted. Local formatting may be associated with the source region of content and the destination region of content. Direct, or emphasis formatting, may be associated with content that has been cut or copied.

Claims

determining, by one or more computing devices, a first set of format attributes, the first set of format attributes indicating local formatting of a first region of content in the electronic document, wherein selected content is a subset of the content in the first region, the content in the first region being a subset of the content in the electronic document, wherein local formatting of another region of the electronic document is different than the local formatting of the first region;

determining, by the one or more computing devices, a second set of local format attributes, the second set of format attributes indicating local formatting of a second region of content in the electronic document, wherein the second region comprises a destination location;

comparing, by the one or more computing devices, the first set of format attributes with the second set of format attributes; and

in response to placing the selected content at the destination location, applying, by the one or more computing devices, to text characters in the selected content, those format attributes of the second set of format attributes that differ from the first set of format attributes.

2. The computer-implemented method of claim 1 further comprising the steps of:

determining marked text characters in the selected content, the marked text characters having direct formatting attributes, wherein text characters in the first region that have the direct formatting attributes are emphasized; and

applying appropriate direct formatting attributes to the marked text characters such that the marked text characters are emphasized after the selected content is placed at the destination location.

3. The computer-implemented method of claim 2 wherein the step of applying the appropriate direct formatting attributes further comprises the step of determining the appropriate direct formatting attributes using the second set of format attributes.
