Keyboard Control for Dark Mode
Power-user controls for the features you use most — configurable in the extension options.
Instant Night Mode Toggle
Flip any page between light and dark with a keyboard shortcut — no need to open the options page.
Dim-the-Lights Shortcut
Trigger the signature dimming overlay from the keyboard — ideal when a video starts and you want instant cinema mode.
Configurable in Options
Shortcut behavior is set in Turn Off the Lights Options, so the controls fit the way you actually work.
Works on Every Site
Shortcuts apply wherever you are — docs, social feeds, video sites, everything.
All Major Browsers
The same shortcuts work in Chrome, Firefox, Edge, Safari, and Opera.
Fully Private
All settings are stored locally in your browser — nothing is sent anywhere.
Why Keyboard Shortcuts for Dark Mode?
If you switch between dark and light often — checking a site's true colors, showing your screen to someone, adjusting to changing light — opening an options page every time is friction you don't need. A shortcut makes it instant.
How to Set It Up
Open Turn Off the Lights Options and look for the shortcut key settings — you can assign keys to toggle Night Mode and to dim the page around a video. From then on, dark mode is one keypress away on any website.
Combine With the Schedule
Shortcuts for the manual moments, the Night Mode schedule for everything else: set dark mode to follow a timer automatically, and use the shortcut only when you want to override it.
Open Source, Private, and Free — Always
Turn Off the Lights collects no personal data, displays no advertising, and charges nothing.

It has been in continuous development since 2009 and remains one of the most trusted browser extensions available, with millions of active users across all major browsers.
