Tab Search brings a Mac Spotlight-style command palette to Chrome. Press Alt+K from any page and a full-screen modal opens instantly — type to search open tabs, bookmarks, and browsing history all at once, then jump to any result with Enter. It's the fastest way to navigate a browser with dozens of tabs open, and the closest thing Chrome has to Arc's command bar.

## How It Works

Alt+K interrupts whatever you're doing and surfaces a search overlay above the current page. As you type, results appear in real time from three sources simultaneously:

1. **Open tabs** — matched by title and URL
2. **Bookmarks** — your full Chrome bookmark library
3. **Browsing history** — recent pages you've visited

The top results from all sources are gathered into a **Best Matches** section at the top of the list, ranked by fuzzy match score. Below that, results stay separated by section so you know exactly where each hit came from.

Select a result and press Enter (or click) to switch to that tab or open that page. If nothing in your local browser matches your query, Tab Search falls through to a web search in a new tab — no mode-switching required.

Press **Escape** to close the palette from anywhere — it registers at the document level, so the input doesn't need to be focused first.

## Settings

| Option | Default | Description |
|--------|---------|-------------|
| Tab Search | On | Enable or disable the feature and Alt+K shortcut |
| Search bar in side panel header | Off | Separate toggle — Alt+K always works regardless |

**Bonus commands with [SuperchargePerformance](/performance/):** If SuperchargePerformance is also installed, Tab Search surfaces three additional commands:

| Command | Action |
|---------|--------|
| Suspend all tabs | Frees memory across your whole session immediately |
| Toggle site whitelist | Add or remove the current site from the Performance whitelist |
| Toggle SuperchargePerformance | Turn the performance extension on or off without opening its popup |

## When to Use This

**Deep tab sessions:** You have 40 tabs open and can't find the one you need. Alt+K → type a keyword from the page title → Enter. Done in two seconds.

**Bookmark retrieval:** Instead of navigating Chrome's bookmark manager, type the name of what you bookmarked and jump directly to it.

**Quick navigation without a mouse:** Keyboard-first users can browse, search, and navigate Chrome entirely from the keyboard. Tab Search is the missing piece that makes this practical.

**Replacing browser address bar habits:** For sites you visit often, Alt+K is faster than clicking the address bar and typing a URL — especially for pages already open in a tab.

## Privacy

Tab Search reads tab titles, URLs, bookmarks, and history from Chrome's local APIs to build search results. No search queries or browsing data are sent to any server. Everything runs locally in the browser.
