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 instance when I'm typing code I almost always do my navigation solely through use of the keyboard. In the IDEs mentioned previously I can quickly select blocks of code by holding Shift + Alt then tapping ↑ to extend my cursor across the lines above. I can then hold Shift + Alt + Ctrl and tap ← or → to quickly jump across words and select the chunk of text I want.
In IntelliJ IDEA I have to constantly enable and disable Column Selection Mode using the Shift + Alt + Insert and even then it doesn't quite function as it does in the other IDEs or Text Editors.
Any ideas?
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.
It is also possible to select holding middle mouse key.
Multiline Caret (without mouse)
Windows/Linux: CTRL + CTRL(Hold) + ↑ / ↓
Mac: ⌘ + ⌘(Hold) + ↑ / ↓
ESC will end multiline mode.
Change Multi-caret Hotkey
To add a custom Keymap, CTRL+SHIFT+A, type keymap and click on the one with Settings as subtext. Search for Clone Caret Above and Clone Caret Below.
I mapped mine to ALT+SHIFT+↑ / ↓.
Bonus
Try holding combinations of CTRL, SHIFT, and arrows for improved selection power.
Go to the Settings | Keymap and set a shortcut for Clone Caret Above and for Clone Caret Below
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.
In Windows or Linux I press two times Ctrl
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! :)
On a mac (with default keyboard mappings):
⇧⌘8
For Mac cmd+shift+* didn't work for me. I changed the keymap to something else and now it works seamlessly.
Most convenient way is to hold Option+Shift and click with mouse.
I installed Idea VIM as one of the plugins which was stopping me doing what I wanted. I uninstalled that and all is fine.
