Zen Browser Keyboard Shortcuts
Zen Browser is built directly on Firefox's Gecko engine, so it inherits the vast majority of Firefox's core keyboard shortcuts — new tab, close tab, private browsing, DevTools — completely unchanged, while layering its own distinctive interface on top: Workspaces for separating tab sets by context (conceptually similar to Arc's Spaces), a built-in split-view for viewing two tabs side by side in one window, and a Compact mode that trims visual padding across the whole interface for a denser layout. The practical result is that anyone who already knows Firefox's shortcuts arrives at Zen already knowing perhaps three-quarters of what they need, with only the Workspaces and split-view layer being genuinely new vocabulary to learn. Being a smaller, community-driven project rather than a corporately funded browser, some of Zen's own distinctive shortcuts have had their default keybindings adjusted more actively between releases than a longer-established browser's stable shortcut set typically would — checking Zen's own settings/shortcuts page for your specific installed version is worth doing if a binding documented here doesn't match what you're seeing. Because Zen's roadmap depends more heavily on volunteer contributor availability than a browser backed by Google, Microsoft, or Mozilla directly, Compact mode and the calmer default aesthetic are worth understanding as two separate, independently toggleable choices rather than one fixed visual identity — someone who likes Zen's Workspaces and split-view concept but wants a denser, more information-rich screen doesn't have to choose between the two. The underlying Firefox engine itself, including its security patch cadence, stays current with Mozilla's own release schedule regardless of Zen's own development pace, since Zen tracks and rebases on top of Firefox releases rather than maintaining a forked engine independently. Anyone evaluating Zen specifically for its Workspaces and split-view features should expect the deepest, most current source of truth for those two specific areas to be Zen's own in-app keyboard shortcuts settings page rather than any single piece of external documentation, precisely because that's the part of the browser evolving fastest.
Workspaces
| Action | Windows | Mac | Description |
|---|---|---|---|
| Create new Workspace | Ctrl+Shift+A (varies by version) | Cmd+Shift+A | Creates a new Workspace, Zen's concept of a separate, named collection of tabs for different contexts, similar in spirit to Arc's Spaces feature. |
| Switch to next Workspace | Ctrl+Tab (varies) or sidebar click | Cmd+Option+Right | Advances to the next Workspace in order, replacing the visible tabs with whatever set belongs to the Workspace you land on. |
| Switch to previous Workspace | Ctrl+Alt+Left (varies) | Cmd+Option+Left | Switches to the previous browser-level Workspace, a Zen-specific concept distinct from an OS window-manager workspace — each one holds its own independent set of tabs and can carry its own accent color and icon. |
| Toggle sidebar | Ctrl+B | Cmd+B | Shows or hides Zen's sidebar, which hosts Workspaces and tabs in a vertical layout distinct from Firefox's traditional horizontal top tab bar. |
| Toggle Compact mode | Settings > Appearance > Compact mode (togglable toolbar icon in most builds) | — | Shrinks the spacing around toolbar and tab elements to fit noticeably more on screen at once, a welcome option on a small laptop display where Zen's roomier default layout starts to feel wasteful. |
Split View Tabs
| Action | Windows | Mac | Description |
|---|---|---|---|
| Enable split view with another tab | Drag tab to split, or Ctrl+Shift+\\ | Cmd+Shift+\\ | Splits the current window to display two tabs side by side simultaneously, a Zen-distinctive feature not present in stock Firefox, useful for comparing two pages or referencing documentation while working in another tab. |
| Exit split view | Ctrl+Shift+\\ (toggle) or close one pane | Cmd+Shift+\\ | Returns to a single-tab view, either by toggling the same split-view shortcut again or by closing one of the two split panes directly. |
Firefox Inherited
| Action | Windows | Mac | Description |
|---|---|---|---|
| New tab | Ctrl+T | Cmd+T | Opens a new tab within the current Workspace, inherited directly and unchanged from Firefox's own shortcut. |
| New private window | Ctrl+Shift+P | Cmd+Shift+P | Opens a new private browsing window, using Firefox's original private-window key rather than Chrome's differing Ctrl+Shift+N convention, since Zen is Firefox-based. |
| Open Developer Tools | F12 or Ctrl+Shift+I | Cmd+Option+I | Opens the browser's DevTools panel, inherited unchanged from Firefox's own developer tooling. |
| Toggle Reader View | F9 | F9 | Toggles Firefox's native Reader View for a distraction-free reading layout, inherited directly since Zen shares Firefox's built-in reading mode rather than building its own separate implementation. |
| Close current tab | Ctrl+W | Cmd+W | Closes the active tab, inherited directly from Firefox's own identical shortcut. |
| Reopen last closed tab | Ctrl+Shift+T | Cmd+Shift+T | Brings back whichever tab you closed most recently, scroll position and history intact, unchanged from how the same key works in stock Firefox. |
Frequently Asked Questions
Why do some Zen-specific shortcuts note that they 'vary by version'?
Zen Browser is a smaller, actively developed community project with a faster and less formally stabilized release cadence than mainstream browsers like Firefox or Chrome, meaning its own distinctive features (Workspaces, split view) have had their specific default keybindings adjusted between releases more than a longer-established browser's core shortcuts typically would — checking Zen's own in-app keyboard shortcuts reference for your installed version is worth doing if a specific binding doesn't match what's documented here.
Is split view the same thing as having two separate browser windows open side by side?
Conceptually similar in outcome but implemented differently — split view keeps both tabs within a single Zen window divided into two panes, which some users find cleaner for window management (one taskbar/dock entry, one set of window controls) compared to genuinely separate OS-level windows that need to be manually resized and positioned side by side independently.
Does Zen Browser support Firefox extensions?
Yes — because Zen is built on Firefox's underlying engine (Gecko) and codebase, it supports the same Firefox extension ecosystem, meaning most Firefox add-ons install and function normally in Zen as well, which is part of Zen's broader value proposition of offering a customized experience without sacrificing compatibility with the existing Firefox extension library.
Can I make Zen's interface more compact if the default spacing feels too roomy?
Yes — Compact mode is a separate toggle from Workspaces and split-view, so you can turn it on independently whenever screen real estate is tight. It tightens up the padding around toolbar and tab elements specifically, which matters most on a smaller laptop display where Zen's roomier default spacing starts to eat into usable space.
Is Zen Browser as reliably supported long-term as Firefox or Chrome?
Somewhat less so than Chrome, Edge, or Firefox itself, since Zen doesn't have a company payroll guaranteeing a release cadence — new features and bug fixes ship whenever volunteer contributors have time to build and review them. It's built directly on Firefox's engine though, so the underlying browser core stays current with Mozilla's own security patches regardless of Zen's own release pace; what could lag is the polish layer Zen adds on top, like Workspaces and split-view, if community momentum slows.
Do basic tab shortcuts like closing and reopening a tab work identically to Firefox?
Yes, since Zen is built directly on Firefox's engine, basic tab-management shortcuts like closing a tab or reopening the last closed one are inherited completely unchanged from Firefox's own conventions, with Zen's own distinctive additions layered on top rather than replacing them.
Does Zen Browser have a shortcut for toggling its distraction-free Zen Mode?
Yes — Zen Mode, which hides the tab bar and other browser chrome for a cleaner reading or focus experience, toggles through the compact-mode icon in the toolbar; some builds also allow binding it to a custom keyboard shortcut through Zen's own settings panel, though there isn't a universal default key across every version.
Is Zen Browser available for Windows, Mac, and Linux?
Yes, Zen Browser is available across all three major desktop platforms, consistent with its Firefox-based foundation which has long supported cross-platform builds — the Firefox-inherited shortcuts covered here work identically on all three, with only the Ctrl/Cmd modifier swapping between Windows/Linux and Mac.
Does Zen Browser include tracking protection or ad blocking by default?
Since Zen builds directly on Firefox, it inherits Firefox's built-in tracking protection features out of the box, and users can add the same content-blocking extensions available in the Firefox add-on ecosystem for more aggressive ad blocking beyond the defaults, without needing a Zen-specific alternative.
