Project: QGIS
Version: 3.10 LTR
We're passionate about making QGIS a user-friendly cartographic tool which is a joy to work with, so we've added a bunch of new shortcuts throughout the interface which allow you to copy and paste symbols from one part of QGIS to another. E.g, you can copy a symbol from a category and paste it directly onto another category, or a layout shape item, or inside the style manager dialog!
