Method and system for checking documents spell

In an embodiment, a subset of a document that includes data blocks is marked by begin ignore tags and end ignore tags. A subsequent spell check operation checks the spelling accuracy of a complement of the subset and ignores the spelling accuracy of the subset. In an embodiment, the data blocks are copied from selected origin locations in the document or another document to a buffer and then pasted from the buffer to the document. The data blocks are then marked to be ignored in response to an ignore spell check option associated with a paste command. In another embodiments, the data blocks are selected and marked in response to an ignore option associated with an edit command. In this way, spell checking of subsets of a document may be selectively enabled and disabled.
