 **What this is:** mpv is the video player SubMiner overlays subtitles on. The SubMiner mpv plugin is a small Lua script that runs *inside* mpv and gives you in-player keybindings to control the SubMiner overlay (start/stop/toggle, skip intro, etc.) without leaving the player window.
 
-**Who needs this page:** Most users never touch the plugin directly — SubMiner-managed launches (the app, the `subminer` launcher, or the Windows shortcut) inject the bundled plugin automatically for that session, so there is nothing to install into mpv's global `scripts` directory. Read on if you launch mpv from another tool and want SubMiner's in-player controls, or you want to script mpv against SubMiner.

 The plugin ships as a modular Lua package under `plugin/subminer/` (entry point `init.lua`, which loads `main.lua` and sibling modules). Earlier releases shipped a single global `main.lua`; runtime loading replaces it.

 Because the bindings come from the same configuration the overlay uses, you maintain one set of shortcuts for both surfaces.

+- Accelerators are normalized per platform - `CommandOrControl` resolves to `Cmd` on macOS and `Ctrl` elsewhere.
 - Multi-line actions (`copySubtitleMultiple`, `mineSentenceMultiple`) register temporary `1`–`9` digit follow-up bindings after the trigger key, with `Esc` to cancel.
 - If two shortcuts compile to the same key, or an accelerator can't be mapped to an mpv key, the app logs a warning and skips that binding instead of registering a broken one.
