A Case of multiple selections

Since IntelliJ IDEA 13.1 (and Android Studio versions based upon that), you can have multiple cursors in your IDE, similarly to what you can do in Sublime Text. To get multiple cursors, the easiest but least convenient way is to hold Alt-Shift and click where you want a new cursor.

But in here we’re all about the keyboard shortcuts, and so I’m happy to say, the IDE has got you covered there as well. A simple Ctrl-G (Alt-J on Win/Linux) will select the next occurrence of the token your cursor is on (or of the current selection). You can also do Ctrl-Shift-G (or Alt-Shift-J) to undo the last selection if you notice you’ve gotten too far. Lastly, Ctrl-Cmd-G (Ctrl-Shift-Alt-J for non-Mac users) will select all occurrences.

Once you have multiple cursors, you can simply start typing normally, and it’ll affect all the cursors. For example, you can move the cursors around, type new stuff, and so on:

But what has this to do with changing case?
