Once I have protected a sheet leaving unprotected cell to allow users chsnge
or input data, users of this sheet do not know which cells they can change
(unprotected) unless they try to click on every cell and are allowed to
change the data in it.
My question is: is there a way to display protected or unprotected sheet and
if there is how to do it; and whether we can control the movement of the
cursor in a protected sheet.
