  } else if (selection.extentOffset < length) {
    newOffset = selection.extentOffset + 1;
  } else {
    newOffset = length;
  }

  if (isShiftPressed) {
    setSelectionSilently(
      TextSelection(
        baseOffset: selection.baseOffset,
        extentOffset: newOffset,
      ),
    );
  } else {
    setSelectionSilently(TextSelection.collapsed(offset: newOffset));
  }
