Arc Command Bar in Chrome: How to Replicate It (2026)

Arc’s Command Bar (Cmd+T) is a keyboard overlay that searches open tabs, switches between them, and jumps to Spaces. Chrome has no native equivalent. The closest match is SuperchargeNavigation’s Alt+K command palette: a fuzzy-search overlay that finds and switches tabs across all windows, reopens closed tabs, switches workspaces, and types a URL or web search. Setup takes about two minutes.

You hit Cmd+T in Arc and the whole browser bent around it. Type three letters, the right tab surfaced, hit Enter, you were there. No reaching for the mouse, no scanning a strip of 40 tab favicons, no losing your place. Then Arc went into maintenance mode and the muscle memory had nowhere to land. Chrome’s Ctrl+T just opens a blank tab. The reflex that made you fast is the one Chrome doesn’t have.

What Arc’s Command Bar Actually Did

Arc rebuilt navigation around one keystroke. Cmd+T opened a centered overlay that did four jobs at once:

• Find an open tab by typing part of its title, across every Space.
• Switch to it with Enter, no clicking.
• Open a new tab or search if nothing matched.
• Jump to a Space (Arc’s named workspaces) from the same bar.

The point wasn’t any single feature. It was that one shortcut replaced four separate Chrome habits: Ctrl+Tab cycling, clicking the tab strip, Ctrl+L for the address bar, and hunting for the right window. Speed came from collapsing all of that into a single fuzzy-search field you never had to aim a cursor at.

That’s the workflow people miss. Not the visual design. The keystroke.

The Closest Chrome Match: Alt+K

Chrome’s own tab search (the small dropdown arrow, or Ctrl+Shift+A) finds tabs but does nothing else, and it’s slow to reach. SuperchargeNavigation maps the fuller Arc pattern onto a single shortcut: Alt+K.

Press Alt+K on any page and a search overlay opens. Type, and it fuzzy-matches:

Type a URL into the Alt+K palette and it offers to open that address; type anything else and it offers a web search. The palette also matches your bookmarks and history alongside open tabs, so one typed fragment surfaces all of them at once. The single difference from Arc: a typed URL or search opens in a fresh tab rather than navigating the current one inline the way Arc’s merged bar did. Everything that made the Command Bar fast for moving between things you already had open is here.

The extension is free, stores everything locally, and needs no account. As of June 2026 the Chrome Web Store version is 1.3.0.

How to Set It Up

Three steps, and the shortcut works on the next page you open.

1. Install SuperchargeNavigation from the Chrome Web Store. It’s free; there’s no sign-in.
2. Open any normal web page (not a chrome:// settings page — extensions can’t run there) and press Alt+K. The command palette opens centered, ready for input.
3. Type a few letters of a tab’s title. Use the arrow keys to move through matches, then press Enter to switch to that tab.

That’s the core loop. The first time it’ll feel like Cmd+T with a different key. After a day it’s the same reflex.

Rebuild the Rest of the Arc Workflow

The Command Bar was one piece of Arc. If you switched to it, you probably want the Spaces and peek behaviour too, and the same extension carries them.

• Spaces become workspaces. Create named workspaces, each with its own isolated set of tabs. Switch between them from inside the Alt+K palette (“Switch to workspace”) or the side panel.
• New Space on the fly. The palette’s “New empty workspace” command spins up a clean workspace without leaving the keyboard, mirroring how Arc let you create a Space from the bar.
• Peek previews. Alt+Click a link to preview it in an inline overlay instead of opening a full tab, the closest thing to Arc’s Peek.
• Session snapshots. SuperchargeNavigation auto-saves your tab state on a rolling 5-minute interval (50 snapshots, roughly four hours of history), so a misfired close isn’t permanent.

None of this needs an account or sends your tab data anywhere. It runs locally in Chrome.

Where It Won’t Match Arc

Two Arc behaviors don’t carry over:

The Alt+K palette does type URLs and run web searches, but it opens them in a new tab rather than navigating the current one inline. In Arc, one bar did both “find a tab” and “go to a URL” in place. In Chrome, the palette still covers both jobs; the omnibox (Ctrl+L) stays the way to navigate the tab you’re already on. If your fingers learned a single bar for everything, that in-place navigation is the small adjustment.

It also doesn’t replicate Arc-only actions. Boosts (per-site CSS/JS tweaks), Little Arc mini-windows, and Arc’s specific command actions have no extension equivalent. Those were browser-level features, not tab navigation.

And the shortcut is Alt+K, not Cmd+T. Chrome reserves Ctrl+T for new-tab at the browser level, so an extension can’t bind to it. You’re retraining one finger, not the whole hand.

Is This Worth It Over Just Switching Browsers

If you’re weighing Chrome-plus-extension against moving to Zen or another Arc-like browser, the deciding factor is usually extensions. Arc and Chrome share the Chromium extension ecosystem; Zen is Firefox-based and doesn’t run Chrome extensions. Staying on Chrome keeps every extension you’ve configured and every Chromium-only workflow your job might require.

The trade is one extra keystroke for URL entry against keeping your entire extension setup and a browser that’s still actively developed. For most ex-Arc users whose Command Bar use was mostly tab-switching, that math favours Chrome.

If your Arc workflow was built on the Command Bar and Spaces, install SuperchargeNavigation, learn Alt+K, and you’ve recovered the reflex. If it was built on Boosts or Little Arc, there’s no Chrome equivalent, and a Firefox-based browser like Zen is the closer fit, extension cost accepted.
