You have several options available to modify input text. You can add additional entries to be displayed in Know It? and Do It! modes, replace input text in all three modes, delete entries, change the default entry, or clear the string input list. In addition, the available options allow you to have multiple “concrete” entries, which are specific text that can be entered, and several “meta” entries, which allow for a range of non-specified text in Know It? and Do It! modes. You must have at least one concrete entry in the Input text list for every string input action.
