Hi,

It is possible to select a cell even though the cell bracket is not 
visible. I modify my MENUSETUP.TR file with a text editor (but take a 
backup first!) to contain an extra menu item thus:

       Item["Select Cell",FrontEndExecute[
                               Module[{Set[nb,InputNotebook[]]},
                               SelectionMove[nb,All,Cell];
                               ]

Obviously, you have to chose which main menu to attach it to.

Be very careful - if you get the file wrong Mathematica will not start.

You can use & characters in the menu item name to create an alt-shortcut
under Windows.

After you have selected a cell - even though it is not visible - you can 
cut/copy/delete it.
