The code supporting starting and ending codes in different cells is below.

This kind of selection (from the starting cell till the end of the row; then all cells in the rows between; then cells till the ending cell) is not natural for TRichViewEdit: TRichViewEdit selects cell that are inside the ...

What does "content between cells" mean? If the cells are in different rows ...

The main problem in this code is re-adding existing items. You take an existing item (using GetItem method) and add it in another place (using AddItemAsIs or AddItem).
You cannot do it. Items are owned by the document. If an item is inserted several times, when the document is freed, the item will ...

Changing TRVAControlPanel.Language is not enough. You need to call additional code to update controls after changing TRVAControlPanel.Language.
In ActionTest demos, this additional code is in the form's Localize method.
