Qt Creator: Multi line text editing

Question

How can I enable multi line text editing for the Qt Creator as known from Code Blocks or Microsoft Visual Studio. You know when you hold the Shift + Alt Key and then press the Down arrow to select multiple lines. Then you can edit multiple lines by typing.

Answer 1

Figured this out just after starting a bounty:

With the mouse, make sure you've already highlighted a character before holding alt. From here it works exactly like Visual Studio.

With the keyboard, hold shift+alt and move around with the arrow keys. You can move down or up lines.
