In the text view mode, your definitions file is provided in a standard Windows Rich Text Editor control:
This has very simple editing features, so please don't expect it to be as comprehensive as a "typical" editor.
If you have considerable text-based editing requirements then you should save your work, then open your definitions file in your favorite programmer's editor rather than use the text view.
Clipboard Operations
Note that while there is currently no "Find" functionality in the Text View, there is clipboard support through the standard clipboard accelerator keys:
Control-C | Copy selected text to clipboard |
Control-X | Cut selected text to clipboard |
Control-V | Copy from clipboard to current selection |
Undo Support
At present, there is single-operation undo in the XML edit mode. There is full undo/redo support planned for a future version of the Mapper tool.
