Roku - Kernel Media Server

The Roku app is remote-first: everything below maps to a button on the standard Roku remote. Features not listed here (channel number entry, the Replay key, Channel Up/Down, an in-app audio/subtitle picker) aren’t implemented yet.

Live TV

Action	How
Previous channel	Press Down twice quickly (within ~0.4s) while watching live TV. Toggles between the current and previously-tuned channel.
Guide overlay (while watching)	Press Up to open a see-through guide over the video. OK on a channel tunes to it. Back returns to the category tabs; Back again closes the overlay.
Favorite / Unfavorite a channel	While the Guide is open, press *Options () to open a dialog with Favorite Channel (or Unfavorite Channel), Record Program, and Cancel**. This acts on whichever channel/program is currently focused.
Record a program	Same *Options () dialog as favoriting. Record Program** only appears for programs that haven’t started yet.
Favorites category	Once you’ve favorited at least one channel, a Favorites tab appears first in the category list on both the Guide and the Channels screen.
Search	Press Up from the Guide’s category tabs to reach the search box.
Stop watching	Press Back to stop playback and return to the screen you came from.

Picture-in-picture (PiP) channels

If your admin has set up a PiP channel (multiple audio sources on one channel), double-pressing Down while watching it cycles between audio sources instead of switching channels, with a toast showing which source is now playing.

On-demand (movies & TV)

Action	How
Resume / Restart	The movie detail screen shows Resume from HH:MM:SS (with a separate Restart button) once you have progress saved, or just Play if you don’t.
Seek	Use the remote’s Rewind / Fast Forward (or Left/Right) during playback. This is Roku’s built-in trick-play.
Skip Intro / Skip Credits	A button appears automatically during the intro or credits. Press OK to skip (to the end of the intro, or to just before the episode/movie ends for credits); it also auto-hides after 8 seconds if you ignore it.
Sort & filter	On the Movies/TV Shows grid: sort by title, year, rating, date added, and more; filter by genre, year, content rating, studio, or network.
A-Z jump	Press Right from the grid to open an alphabet jump strip.

Recordings

Press Options (*) on a recording to delete it.

There’s no in-app audio track or subtitle picker on Roku beyond the PiP audio-swap above, and no quality/version picker. These use Roku’s system-level behavior where available.
