Microsoft Word has a very useful command for copying and pasting formatting. Ctrl+Shift+C and Ctrol+Shift+V
Is there such a command available in Libre Office Writer? If not, is there some way of adding it?
Format Paintbrush is your friend:
You can set a (custom) shortcut key to it if you don‘t like clicking it: from the menu, choose Tools - Customize - Keyboard tab (a document must be opened)
