This post made me ponder something. I see no options in Camtasia for manipulating any kind of dictionary. But when you right-click an unrecognized word, you see an option for adding the word to the dictionary. I added a really bizarre word to the dictionary for testing purposes. But after choosing to add it to the dictionary, it still bears a red underline. I would have expected the underlining to disappear once I added the word to the dictionary.
This would seem to beg the following questions: 1. If a dictionary exists, where is it located? Is it possibly a text file that could be manipulated outside of Camtasia? 2. Why doesn't the red underline disappear once you have added the word? 3. Does the process of adding a word to the dictionary even work as it should?
