Font subsitution

Hi,

I have accidentally created a text object while I was moving the playhead with the “decimal” button on the keyboard…I think. Now whenever I open the FLA, it is asking for front substitution. I like to know of a way (ie. find and replace) to find this text object so I can delete it. This piece is rather big so going through each frame and inspecting each layer is prehaps the last, last, last option. Hope someone can help.

TIA
