Previously I used Windows 10 operating system. I am a beginner and I am learning HTML, CSS. I used Visual Studio Code on Windows 10. There I used the shift + alt + arrow-down key to duplicate some selected lines just under the selected lines. I recently shifted to Ubuntu and the shift + alt + arrow-down key is not working like windows. It is not duplicating the selected lines.
How can I make these keys working like windows or is there any other key to do the same work?
Help me, please.
