I understand the RTF standard has some basic support for check-boxes and some other basic objects without embedding external objects. Does TRichView support this, and, if so, how?

In TRichView, you can insert any Delphi control, including TCheckBox.
It can be saved in a native format (RVF). However, saving/reading controls to RTF is not implemented (you can implement saving yourself using OnSaveComponentToFile event)

Thank you Sergey, I suspected as much. Now I just have to figure out what RTF data I have to substitute in place of TCheckBox. Any idea?

The other question is, how do I reverse the process, i.e., load an RTF file which uses native check boxes and replace them with TCheckBox? Is there an appropriate event for this?

Unfortunately - no, I am afraid it is not possible to implement using events. Later, RTF checkboxes will be supported.
