I'm not able to edit the Hunspell dictionary. When I click on Edit User's Spelling Dictionary, I just get a blank window that I can type into, but there are no buttons to confirm entries or anything.
By "entries added to the dictionary yourself" do you mean the glossary?
Aha, I also just found the option of adding a term to the spellcheck dictionary when saving a glossary entry.
I will definitely use the method you just described as well, thanks so much!
I'm wondering where it is too.
@Alyssa: One little remark: Besides the right-clicking method I described above, there are also the items "Show alternative spelling" and "Replace with alternative spelling" in the "Edit" menu (which also have keyboard shortcuts).
Sorry for the confusion. I realized after the fact that what I "discovered" was actually what Martin suggested...I just figured it out while highlighting the terms to add to the Glossary and thus thought that it was a different process. On another note: if you just right-click on a word with a red-line underneath (on a Mac), the spelling options do not show up in a drop-down list. The word has to be highlighted for this to work. That's why I had a difficult time finding this option.
