When I open up the Command Palette (Ctrl or Cmd + P), type in a filename and hit Enter, the file will automatically be opened in Preview mode.

Open File Permanently

What I want is to have an option to open a file permanently from the Command Palette. I am aware of the "workbench.editor.enablePreviewFromQuickOpen" settings, but that will disable Preview mode.

For example, selecting a file in the Command Palette and hitting Ctrl + Enter will open the file as Preview in a new Split view. I am looking for a similar shortcut to open a file permanently.

Correction: I meant the Quick Look mode using Cmd + P / Ctrl + P. The Command Palette is used to run commands, and cannot search or open files.

EDIT (I previously offered a workaround, but there is such a feature!)

Just press the Right arrow when your file is highlighted. The Command Palette stays exactly where it is and your file opens (in non-preview) in the background. You can do this as many times as you like.

What I was looking for was: Settings -> Workbench -> Editor Management

I set Enable Preview and unset Enable Preview from Quick Open which makes VSCode behave like st3.

With Quick Look open, select the file you wish to open permanently
