IntelliJ IDEA - caret behavior

Question

I am trying to figure out one thing in IntelliJ IDEA 10:

1. current caret position
2. where caret moves after pressing DOWN arrow
3. where I want caret to be

Is such setting possible?

Answer 1

File | Settings (or Preferences on Mac) | Editor | Allow placement of caret after end of line:

Answer 2

Please note that this effect can also occur if you activate Column Selection Mode under: Edit -> Column Selection Mode which allows you to make square selections.
