Cannot open new pane from automatic search

After automatic search I wanna open a result in a new pane. This should be done with “Shift + Enter” but this is not working for me. It just inserts the result as an portal in the current document. I does not work for me on desktop and browser (this is why it’s not an issue with any chrome extension disability). Same question like here. What could be the reason for this behaviour?

The shortcut is “command + Shift + P”.
