Chrome Tab Side Panel Shortcut: 3 Toggle Methods (2026)

You need to search across open tabs, the panel is closed, and reaching for the toolbar button on every tab switch adds up. A full vertical sidebar solves the reach but narrows your content width. Chrome’s side panel toggle is Ctrl+Shift+S (Mac: Cmd+Shift+S) since Chrome 114: a ~360px docked column that persists across tabs.

Key takeaways

• The built-in side panel toggle is Ctrl+Shift+S (Windows/Linux) or Cmd+Shift+S (Mac). Available since Chrome 114.
• Rebind any extension shortcut at chrome://extensions/shortcuts. Chrome silently drops a suggested key that collides with another extension, so check the bindings there.
• The side panel is a ~360px docked tool column. Chrome’s vertical sidebar (Chrome 146+) moves your entire tab strip. Pick the surface that matches what you need beside the page.

The Built-In Side Panel Toggle

Chrome’s side panel is a native UI surface that shipped in Chrome 107. It is a docked vertical column, approximately 360px wide, right-docked by default. You cannot detach or float it. It is window-scoped: the panel stays open as you switch tabs within the same window.

The toggle shortcut is Ctrl+Shift+S on Windows and Linux, Cmd+Shift+S on Mac. This shipped in Chrome 114 and has not changed. A toolbar button offers the same action: right-click the toolbar, check “Show side panel button,” and the icon appears in the strip.

The panel holds Chrome’s own tools: Bookmarks, Reading list, History, and Shopping. Only one extension panel shows at a time. You select which one from the panel header.

Step 1: Open the Side Panel

Press Ctrl+Shift+S (or Cmd+Shift+S on Mac) to toggle the panel open or closed. One press opens it, a second press closes it. The panel appears on the right edge of your window by default.

If you prefer a toolbar button over the shortcut: right-click anywhere on the toolbar, find “Show side panel button” in the context menu, and toggle it on. The button sits in the toolbar from then on.

To move the panel to the left edge: open Settings, go to Appearance, and change the Side panel setting. The panel stays docked; only the side changes.

Step 2: Rebind the Shortcut

What you can rebind are extension command shortcuts. If you install an extension that offers its own side panel toggle (SuperchargeNavigation uses Alt+B), that key is a suggested default. Chrome assigns it on install, but you can change it.

Open chrome://extensions/shortcuts in a new tab. You will see extension command shortcuts and their current key bindings. Find the command you want to change and enter the new key combination for it.

One constraint to know: an extension may specify at most 4 suggested shortcuts. If an extension’s suggested key collides with another extension’s command, Chrome silently drops the suggested key. No error message, no warning. Test the new key after you set it.

Side Panel vs Vertical Sidebar

Chrome 146 (March 2026) shipped vertical tabs to stable. The flag-free rollout completed in April 2026, and on current stable (Chrome 155) it is a normal setting: Settings → Appearance → Tab position → Side. A legacy fallback exists at chrome://flags/#vertical-tabs for older builds.

The two surfaces solve different problems. Here is the comparison:

If you need tools beside the page (a bookmark list, a reading queue, a shopping comparison) without covering your content, the side panel is the right surface. If you need to see tab titles at a glance without scrolling a horizontal strip, the vertical sidebar is the simpler move.

Four Keys for Tab Tools in the Panel

The built-in panel holds Chrome’s own tools. If you want your own tab tools in that panel space: search across all open tabs, group them, bulk-pin or bulk-close, SuperchargeNavigation (v1.4.2) opens the side panel with four bound keys.

The panel itself shows a vertical tab list with full titles (not just favicons), a workspace switcher, and multi-select bulk actions: pin, unpin, mute, unmute, group, lock group, close. Alt+B opens or closes this panel. Because it uses chrome.sidePanel.open({ windowId }), the panel is window-scoped: it stays open as you switch tabs, the same behavior as the built-in panel.

All four keys are suggested defaults. Rebind any of them at chrome://extensions/shortcuts. If a key collides with another extension, Chrome drops it silently.

Pick Your Surface

If you want Chrome’s own tools (bookmarks, reading list, shopping) beside the page, the built-in panel with its toolbar button is the tool. Press Ctrl+Shift+S and leave it there.

If you want tab search, smart grouping, and bulk actions in that same panel space, SuperchargeNavigation’s Alt+B opens its own panel with those tab tools next to your content. The key is a suggested default, not fixed: rebind it if Alt+B fights another habit.

If you just need to see more tab titles without covering content, flip the vertical sidebar setting: Settings → Appearance → Tab position → Side. It is the lowest-effort move and needs no extension.
