Multi-caret mode in IntelliJ Idea

After seeing it used very effectively in several screencasts I finally decided to learn the keyboard shortcuts to for multi-line/multi-caret selection and editing in IntelliJ Idea.

There are two ways how to go about it:

  1. Switch from line-selection mode to column-selection mode, by default Alt + Shift + Insert and then hold Shift and press an up/down arrow key to spread the caret to as many lines as you need, or
  2. Press Ctrl, release it, press Ctrl again and hold it and press an up/down arrow key again as much as you need

Personally, I like the first one even though it seems bit more cumbersome.

MacOS keys are obviously different. Details are in the official documentation.
