How do I find all the subtables that contain a given glyph?

[Bearpecs]

I have added a glyph which should have the same features and properties as an existing glyph. I want to be sure that the new glyph gets into every subtable that the existing glyph is in. How can I identify all those subtables?
Many thanks.

Click the Code Editor button at the bottom of the OpenType Designer window. Then use the Search feature to look for the glyph name. Press the F3 key to look for subsequent finds.
