Open any Writer file, format a paragraph (~oa) or edit the style (r-click>modify). if the cursor is to the right, Backspace deletes the last char (OK) and puts the cursor in 1st position, to the left (idiotic). Then, when one enters a char, the cursor returns every time to its 1st position, so that entering "123" gives '321' To obtain '123', one must reposition the cursor at the right after each char. Editing other parameters, such as Indent or Spacing, is normal.
