Does this help?
Click the first sheet tab, hold down <Ctrl>, click in last sheet tab.
Now, navigate to desired cell and click in it.
That cell is now the cell of focus in *all* your sheets.
Right click in a tab and choose "Ungroup Sheets".
When you click in any sheet tab, you'll find that the cell you selected when
the sheets were "Grouped", is now selected in all the sheets.
