Intellij Idea - how to get rid of thick caret/cursor

Question

I pressed something in Intellij and my caret shape changed to this. How to revert to the normal thickness? Using Intellij 2016.1.

Compare to this, normal thickness should be that of a bold vertical line:

Update: On Android Studio 2.1 beta, same machine, same font settings, cursor is visibly thinner.

Answer 1

You can .. but it's not pixel perfect. I mean -- for me the value does not seem to control thickness in pixels but rather some index (which gets applied to some predefined values) -- at least this is my impression on what I see my computer.

In any case:

1. Help | Find Action...
2. Search for registry action
3. Once in Registry window -- look for editor.caret.width entry
4. Set the new value (for me the default was 2) -- make sure that field went bold (move to another entry) to ensure that new value was accepted.
5. Restart IDE (this option requires it)
