-Lua should not attempt to edit the buffer as it can cause crashes due to how buffers are setup in this manner. Most of this structure is readonly and should only be used for reference.
+Some fields are read-only and cannot be edited.
+If you edit the 'Buf' field, you must update the BufTextLen to the new length as well as set BufDirty to true in order for it to be properly updated. To do this easily you can make use of the DeleteChars and InsertChars functions which will handle the property adjustments for you.
+You may also want to set CursorPos to the end of the string for a more expected result.
