writer end of paragraph behaviour
If you are at the end of a paragraph in writer and press right arrow or end then this has a special meaning of “revert to underlying style”. i.e. if you have added hard attributes of bold/font/pitch to your text and press right arrow/end at an end of paragraph you’ll see that the various status indicators of those attributes toggle back to their original state and newly typed text is different from the previous text. This is a feature, and a nice one when you know of it to quickly switch back to the unmodified text.
