Keyboard Shortcuts

This page is the complete reference for every keystroke SubMiner responds to. If you are just getting started, focus on the Mining Shortcuts and Overlay Controls sections — those cover the day-to-day mining loop. The rest can wait until you need them.

A few terms used throughout:

• Overlay — the transparent SubMiner window that sits on top of mpv and shows the interactive subtitles. Most shortcuts only work while this window has focus (click the video once if a shortcut seems to do nothing).
• Ctrl/Cmd — use Ctrl on Windows/Linux and Cmd (⌘) on macOS. In the config file this is written as CommandOrControl.
• Accelerator — Electron's name for a shortcut string like Alt+Shift+O.

All shortcuts are configurable in config.jsonc under shortcuts and keybindings. Set any shortcut to null to disable it.

Global Shortcuts

These work system-wide regardless of which window has focus.

Shortcut	Action	Configurable
Alt+Shift+O	Toggle visible overlay	shortcuts.toggleVisibleOverlayGlobal
Alt+Shift+Y	Open Yomitan settings	Fixed (not configurable)

::: tip Global shortcuts are registered with the OS. If they conflict with another application, update them in shortcuts config and restart SubMiner. :::

Mining Shortcuts

These work when the overlay window has focus.

Shortcut	Action	Config key
Ctrl/Cmd+S	Mine current subtitle as sentence card	shortcuts.mineSentence
Ctrl/Cmd+Shift+S	Mine multiple lines (press 1–9 to select count)	shortcuts.mineSentenceMultiple
Ctrl/Cmd+C	Copy current subtitle text	shortcuts.copySubtitle
Ctrl/Cmd+Shift+C	Copy multiple lines (press 1–9 to select count)	shortcuts.copySubtitleMultiple
Ctrl/Cmd+V	Update last Anki card from clipboard text	shortcuts.updateLastCardFromClipboard
Ctrl/Cmd+G	Trigger field grouping (Kiku merge check)	shortcuts.triggerFieldGrouping
Ctrl/Cmd+Shift+A	Mark last card as audio card	shortcuts.markAudioCard

The multi-line shortcuts open a digit selector with a 3-second timeout (shortcuts.multiCopyTimeoutMs). Press 1–9 to select how many recent subtitle lines to combine. When the shortcut starts from mpv, SubMiner focuses the visible overlay for that selector instead of reserving the number keys in the mpv plugin.

Overlay Controls

These control playback and subtitle display. They require overlay window focus.

Shortcut	Action
Space	Toggle mpv pause
F	Toggle fullscreen
V	Cycle primary subtitle bar mode (hidden → visible → hover)
J	Cycle primary subtitle track
Shift+J	Cycle secondary subtitle track
Ctrl+Alt+P	Open playlist browser for current directory + queue
ArrowRight	Seek forward 5 seconds
ArrowLeft	Seek backward 5 seconds
ArrowUp	Seek forward 60 seconds
ArrowDown	Seek backward 60 seconds
Shift+H	Jump to previous subtitle
Shift+L	Jump to next subtitle
Shift+[	Shift subtitle delay to previous subtitle cue
Shift+]	Shift subtitle delay to next subtitle cue
Ctrl+Shift+H	Replay current subtitle (play to end, then pause)
Ctrl+Shift+L	Play next subtitle (jump, play to end, then pause)
Q	Quit mpv
Ctrl+W	Quit mpv
Right-click	Toggle pause (outside subtitle area)
Right-click + drag	Reposition subtitles (on subtitle area)
Ctrl/Cmd+A	Append clipboard video path to mpv playlist

These keybindings can be overridden or disabled via the keybindings config array. The playlist browser opens a split overlay modal with sibling video files on the left and the live mpv playlist on the right.

On macOS managed playback, SubMiner disables mpv's menu-bar shortcuts so configured SubMiner shortcuts like Cmd+Shift+O reach the mpv plugin instead of opening native mpv menu actions.

Mouse-hover playback behavior is configured separately from shortcuts: subtitleStyle.autoPauseVideoOnHover defaults to true (pause on subtitle hover, resume on leave).

Subtitle & Feature Shortcuts

Shortcut	Action	Config key
Ctrl/Cmd+Shift+V	Cycle secondary subtitle mode (hidden → visible → hover)	shortcuts.toggleSecondarySub
Ctrl/Cmd+D	Open loaded character dictionary manager	shortcuts.openCharacterDictionaryManager
Ctrl/Cmd+Shift+O	Open runtime options palette	shortcuts.openRuntimeOptions
Ctrl/Cmd+/	Open session help modal	shortcuts.openSessionHelp
Ctrl+Shift+J	Open Jimaku subtitle search modal	shortcuts.openJimaku
Ctrl+Alt+C	Open the manual YouTube subtitle picker	keybindings
Ctrl+Alt+S	Open subtitle sync (subsync) modal	shortcuts.triggerSubsync
\	Toggle subtitle sidebar	subtitleSidebar.toggleKey
`	Toggle stats overlay	stats.toggleKey

The stats toggle is handled inside the focused visible overlay window. It is configurable through the top-level stats.toggleKey setting and defaults to Backquote.

The subtitle sidebar toggle is overlay-local and only opens when SubMiner has a parsed cue list for the active subtitle source.

Controller Shortcuts

These overlay-local shortcuts open controller utilities for the Chrome Gamepad API integration.

Shortcut	Action	Configurable
Alt+C	Open controller config + remap modal	shortcuts.openControllerSelect
Alt+Shift+C	Open controller debug modal	shortcuts.openControllerDebug

Controller input only drives the overlay while keyboard-only mode is enabled. The controller mapping and tuning live under the top-level controller config block; keyboard-only mode still works normally without a controller.

MPV Plugin Chords

When the mpv plugin is installed, all commands use a y chord prefix — press y, then the second key within 1 second.

Chord	Action
y-y	Open SubMiner menu (OSD)
y-s	Start overlay
y-S	Stop overlay
y-t	Toggle visible overlay
v	Cycle primary subtitle bar mode (hidden → visible → hover)
y-o	Open Yomitan settings
y-r	Restart overlay
y-c	Check overlay status
y-h	Open session help

The bare v plugin binding intentionally overrides mpv's native primary subtitle visibility toggle so it cycles the SubMiner primary subtitle bar (hidden → visible → hover) instead.

When the overlay has focus, press y then d to toggle DevTools (debugging helper).

Drag-and-Drop

Gesture	Action
Drop file(s) onto overlay	Replace current mpv playlist with dropped files
Shift + drop file(s)	Append all dropped files to current mpv playlist

Customizing Shortcuts

All shortcuts.* keys accept Electron accelerator strings, for example "CommandOrControl+D". Use null to disable a shortcut.

{
  "shortcuts": {
    "mineSentence": "CommandOrControl+S",
    "copySubtitle": "CommandOrControl+C",
    "toggleVisibleOverlayGlobal": "Alt+Shift+O",
    "openJimaku": null, // disabled
  },
}

The keybindings array overrides or extends the overlay's built-in key handling for mpv commands:

{
  "keybindings": [
    { "key": "f", "command": ["cycle", "fullscreen"] },
    { "key": "m", "command": ["cycle", "mute"] },
    { "key": "Space", "command": null }, // disable default Space → pause
  ],
}

Both shortcuts, keybindings, and subtitleSidebar are hot-reloadable — changes take effect without restarting SubMiner.
