For one of my current project the customer had the (more than reasonable) requirement that all messages, texts on buttons etc should be displayed in Dutch. And there are really a lot of these messages: Regions, Computations, Validations, Processes etc, they all have their own messages. So that would require a lot of clicking in the APEX Development Environment....until I found out there is a very nice shortcut for that! When you navigate to the Utilities section there is a list on the right side named "Page Specific Utilities". These utilities are subdivided by Region, Button, Item etc.. And when you click on one of those items, there is another menu where you can choose for "Grid Edit...Error Messages". And when using that, you'll be ready in no time! I think it was worth sharing this, just to prevent someone from getting RSI...
