You can "undo" some actions in Dynodex by choosing "Undo", Cmd-Z. The actions you can undo are:
• typing text
• clearing text (Cmd-B)
• copying text (Cmd-C)
• cutting text (Cmd-X)
• pasting text (Cmd-V)
• deleting text (Cmd-minus)
One of the unique aspects of "Undo" in Dynodex is that you can undo the contents of any field at any time before entering the record. For example, if you change "State" from "CA" to "NY" and proceed to type data into other fields, you can return to the "State" field and choose "Undo" to toggle back to "CA".
