Remove excess glyphs

I’ve added extra glyphs to my latin set with the intention that I was going to include diacritics. I now want to remove them, but I cannot find any info of how to do this? Any help please? I know I’ve done it before but cannot find the info?

Does Glyph > Remove Glyph do what you’re intending?

Thank you. Couldn’t see the forest for he trees!
