I would like to be able to select a contiguous set of horizontal cells in a row, take a copy, then paste the values into another row at the same position in the same table. I do not want to copy all the attributes, only a subset, but they are at least contiguous. At the moment I am doing a simple copy-paste cell-by-cell, and it is very time consuming, not to mention frought with error. If it were in a spreadsheet, it would be as simple as highlighting the group of horizontal cells, taking a copy, move the cell cursor down one cell, and then doing a paste. Is this possible without going through an export/edit/import process. Thoughts greatly appreciated. Barrie
There is an existing ArcGIS Idea covering this functionality that you can vote for.
In the meantime a workaround may be as follows:
Personally, I would be more inclined to use the export/edit/import via Excel route that you suggested.
