how to duplicate one line of code in Android Studio?

Issue

I worked by Visual Studio and i want to know how can I duplicate a line in my source code in Android Studio IDE ?

i tried shift+'alt'+`down' but it didnt work :/

Solution

I found that I can do this by pressing Ctrl+D. So cool.

Also you can move a line of code down and up by Ctrl + Shift + Up/down.

On mac systems press Command instead of Ctrl
