I would like to find out which cells have formula dependencies in a large spreadsheet. I am looking for a way to do something like OpenOffice
Tools>Detective>Trace dependents
and
Edit>Find & Replace>Search in formulas
or a way to create a trigger in GAS that gets called when a given cell value is referenced and can identify the source of the reference.

The following code will add a menu to the Spreadsheet:
Detective > Trace Dependents
Selecting this will add a note to the active cell with all dependent cell references.
(added search for static references as suggested by Graham below)
You could add a similar function to the traceDependents function to search for the text within the active cell for a Search in Formulas function. I'll leave that as an exercise for you.
