Is it possible to some how setup IntelliJ IDEA so that I can column select with the cursor keys similarly to how I might in Notepad++, Visual Studio, or FlashDevelop.
<For me on Mac:
Press once 'option' key, release it, and press and hold it again. Now navigate with cursor to select desired code. Press 'Esc' to exit column mode! :)
For Mac cmd+shift+* didn't work for me. I changed the keymap to something else and now it works seamlessly.
In Windows or Linux I press two times Ctrl
I think @Meo's answer is the most correct, but if your hand happens to be on the mouse, you can also accomplish this with Ctrl+Alt+Shift+Left Mouse Button Click. Or look for the Add Rectangular Selection on Mouse Drag in the keymap settings.
It is also possible to select holding middle mouse key.
You can do column editing using the Edit | Column Selection Mode.
The shortcut to turn it on/off is Alt+Shift+Insert. You navigate with arrow keys to select blocks of text.
