# Keyboard shortcuts

{% hint style="info" %}
Trancy's keyboard shortcuts let you control bilingual-subtitle video learning without reaching for the mouse: start Trancy, replay or auto-pause a sentence, switch modes, and resize subtitles straight from the keyboard. On Mac use the Command (⌘) and Option (⌥) keys; on Windows use Control (Ctrl) and Alt.
{% endhint %}

These shortcuts are configurable. Open the Trancy shortcut settings to see your current bindings and reassign any key; on Safari, custom keyboard shortcuts are supported as well.

EDITOR TODO: Most of these bindings were transcribed from a 2-year-old screenshot of the in-product shortcut settings and could not be re-verified live. Only a few are confirmed from official sources: Cmd/Ctrl+E to start (current settings UI), J for auto-pause (changelog V5.0.0), R for loop playback (changelog V7.8.0), and the existence of A/S/D shortcuts in Practice mode plus a translation-backfill shortcut (changelog V7.6.0). Rows marked "(verify)" need confirmation against the live extension, and the two identically labelled "full screen" entries (Alt+W and Alt+F) likely differ (e.g., full screen vs. wide screen) - confirm the exact label for each.
