If you have your toggle status recorded as a cell - call it Status_Cell, then
you can use a conditional format to produce the same effect

If you set the status to TRUE when the file is read only then use
=Status_Cell = TRUE
as a formula condition in the conditional format to apply grey (or anything
else you want)

I posted a q yesterday about this but was unclear in what I was after.
What I would like is for the cells from A7 down to turn grey when the user
toggles to 'read only' using the "Toggle read only" button on a tool bar.
When the user toggles back to read/write, those same cells go back to
unformatted.
The first part can be done using Workbook_open but I need something to work
when the file status changes when the workbook is already opened.

Thanks,
