More Substitutions Than I Can View

Google Doc’s equivalent to Word’s AutoCorrect feature (Tools->Preferences->Substitutions) will correct common spelling mistakes. Great feature, I use it a lot. I’ve used it that much I now have more substitutions than I can see; my list currently stops half-way down the words begging with ‘p’.

  1. Has anyone seen this before, or know a workaround for the problem?

  2. For example, is there a way of importing and exporting substitutions?
