I want to show the contents of a formula.

From the LibreOffice wiki:

Telling libreoffice calc that a

formula is meant to be text:If you

want to fill a spreadsheet cell with

text that looks like a formula,

libreoffice can be hindered from

evaluating this formula by preceeding

this formula by a single quotation

mark (’).

If I do this, the escape character (=the single quote sign) stays visible.

When protecting a number link in ('2012) the escape character is not visible.

I expected the same for the equal sign, but it stays visible. Is this a bug?
