IntelliJ Do not open file in single click

Question

In Mac version of IntelliJ, I see a problem with navigation. Problem is: when I click any file using mouse or select using keyboard from Project view, it automatically opens the file in Editor. Earlier, I've always double-clicked files in Project view to open them in Editor. How do I disable single click open? I tried to verify my KeyMap settings and nothing points to single click open.

Answer 1

After a little research, here is the setting that I've changed earlier inadvertently causing the problem.

Uncheck Autoscroll to Source in Project view settings.

Answer 2

If the Autoscroll to Source answer doesn't help you, it's possible you have the newer Enable Preview Tab feature enabled.

Disabling this option will allow you to single-click on items without opening a new preview pane.
