What application can be used to quickly view files in KDE?

Question

linux

Now switched to Manjaro KDE, used to be on Manjaro Gnome. Here in gnome there was an application for quickly viewing files (as on Mac / MacOS) (that is, you need to press the spacebar and display the contents of the file). What application can be used?

Answer 1

Dolphin
This is a file manager, it seems to be the default in KDE. In it menu - view - panels - information. Or press F11. It will show a preview of almost all files on the right - both pdf, and office, and all sorts of xml, and pictures, and music, too.
