TV On-Screen Keyboard

The keyboard that opens for text fields on TV has a few tools beyond the letter grid:

  • Caret keys (‹ and ›) move the cursor through the text, so you can fix a typo in place. Holding OK keeps the caret walking.
  • Backspace: holding OK keeps deleting. On touch screens, a long press clears the whole field.
  • Paste key (clipboard icon) inserts the clipboard at the cursor. Handy for server addresses or passwords copied from a password manager.
  • Accents and extra symbols: keys marked with a small dot hold more characters. Hold OK on the key (or long press on touch), then pick with the direction keys.
  • Suggestion chips above the keys offer recent searches, previously used usernames at sign-in, and known server addresses. Passwords never show suggestions.
  • Number pad: numeric fields such as PINs and ports get a large phone-style pad.
  • Layouts follow the app language, with AZERTY for French and QWERTZ for German, Czech, Slovak, Hungarian, Croatian, and Slovenian.
  • System keyboard key hands the field to the platform keyboard, for voice input or other languages.

Subtitle Downloads

Download subtitles from the item details screen:

  1. Open any Movie or Episode details screen.
  2. Find the Subtitles section in the details area.
  3. Tap or click the download icon next to the subtitles you want.

Downloaded subtitles are saved with your media and work offline automatically.

Advanced: telling similar tracks apart

Each search result carries badges under its name saying what it actually is: SDH, AI Translated, Machine Translated, and the frame rate it was timed against. That lets you tell two similarly named tracks apart before downloading either. Synchronized timing is preserved during download, and you can pick your preferred format (SRT, ASS, VTT) from what your server offers.

Remote Device Control

Control other Jellyfin devices on your network from Moonfin:

  1. Tap or click the user avatar in the top toolbar.
  2. Select Remote Control from the menu.
  3. Pick a device from the list. Each shows its name, playback status, and a device type icon.
  4. Send it commands: play something on it, pause, stop, change volume, or seek.
Advanced: what has to be true for this to work
  • Works with desktop clients, mobile apps, web players, smart TV apps, and other Jellyfin-compatible players.
  • The target device must be registered with your Jellyfin server, online, and connected to the same server instance.
  • You must have playback permission for the content.
