Keyboard shortcut for small git diff popup as seen when clicked on the gutter marker?

Question

I sometimes want to see the diff of what has changed only per line, but I find it uncomfortable to always move your hand to the mouse and click on the gutter marker. Is there a way to assign a shortcut to open that little diff window (as seen in the image)? I couldn't find an IntelliJ action that opens it.

Answer 1

That action is called Change Under Caret.

By default, no shortcut is assigned to it. You can find it with Find Action (Ctrl+Shift+A | ⇧⌘A).

You can also assign a shortcut to it right in this popup with Alt+Enter | ⌥⏎.
