Table target cell ID control

Many times when looking carefully at certain values of a very large table I find myself scrolling endlessly to the appropriate table entry.
It would be extremely helpful if I could enter in a table row (and/or column, layer etc.) number and have the table center on that value, meaning that the cell in question would be brought to the center (or upper corner) of the table window.
It seems like this feature is halfway implemented already in that when selecting a given cell, I can scroll away and then by clicking on the cell indicator in the upper left corner, that cell is brought back again.
I just want to turn that target cell ID indicator into a control.
Choose Edit->Find, select Row from the Find popup menu, enter the desired row, and click Find.

From the command line you can go to a particular cell like this:
ModifyTable topLeftCell=(50,0)


To set the selection and go to that cell:
ModifyTable selection=(50,0,50,0,50,0), topLeftCell=(50,0)
