Keyboard Shortcuts

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+I`	Toggle invisible overlay	`shortcuts.toggleInvisibleOverlayGlobal`
`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.

Overlay Controls

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

Shortcut	Action
`Space`	Toggle mpv pause
`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
`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.

`Ctrl/Cmd+Shift+V`	Cycle secondary subtitle mode (hidden → visible → hover)	`shortcuts.toggleSecondarySub`
`Ctrl/Cmd+Shift+O`	Open runtime options palette	`shortcuts.openRuntimeOptions`
`Ctrl+Shift+J`	Open Jimaku subtitle search modal	`shortcuts.openJimaku`
`Ctrl+Alt+S`	Open subtitle sync (subsync) modal	`shortcuts.triggerSubsync`

Invisible Subtitle Position Edit Mode

Enter edit mode to fine-tune invisible overlay alignment with mpv's native subtitles.

Shortcut	Action
`Ctrl/Cmd+Shift+P`	Toggle position edit mode
`ArrowKeys` or `hjkl`	Nudge position by 1 px
`Shift+Arrow`	Nudge position by 4 px
`Enter` or `Ctrl+S`	Save position and exit edit mode
`Esc`	Cancel and discard changes

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
`y-i`	Toggle invisible overlay
`y-I`	Show invisible overlay
`y-u`	Hide invisible overlay
`y-o`	Open Yomitan settings
`y-r`	Restart overlay
`y-c`	Check overlay status

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+Shift+M". Use null to disable a shortcut.

{
  "shortcuts": {
    "mineSentence": "CommandOrControl+S",
    "copySubtitle": "CommandOrControl+C",
    "toggleVisibleOverlayGlobal": "Alt+Shift+O",
    "toggleInvisibleOverlayGlobal": "Alt+Shift+I",
    "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 and keybindings are hot-reloadable — changes take effect without restarting SubMiner.
