Can't switch language for USB keyboard on PS4

Hello! I play on PS4 with English interface but my native language is Russian so I often need to type in Russian when I write to my friends in game. I use USB keyboard but I can't change language from English to Russian with "shift+alt", I always need to open virtual keyboard with my controller and it's very inconvenient. How can I change language only with USB keyboard?

Keyboard configuration is in PlayStation settings (at least it is on PS5, I think I remember it being on PS4 too), but they're often less...flexible than on a PC/Mac.

Greetings fellow Eorzean,

In regards to your issue, please go into the Playstation 4's settings under the following section: Settings > Devices > External Keyboard. From there, change to the desired language and hit the ~ key to switch between types. If you are still having issues with this feature, we advise contacting Sony Support for further assistance.
