The guide is inside the extension
Streamline's Help Center is not a website. It is a page the extension serves itself, with live diagnostics
that read your actual settings and a shortcut reference generated from the code that handles the keystrokes.
A copy hosted here would go stale the first time either changed. Three ways in:
-
From the panel
The guide button
Open Streamline from the toolbar or the side panel, then press the guide button in the panel header.
-
On any Twitch page
Right-click menu
Right-click anywhere on twitch.tv and choose Streamline help.
-
From the keyboard
Alt+Shift+S
Opens the panel, from where the guide button is one click away.
Inside you will find ten sections: getting started, filtering and rules, watching, chat, audio, appearance,
stats and history, data and backups, keyboard shortcuts, and troubleshooting.
Troubleshooting
These four cover almost everything people write in about. Each one is also in the extension's
troubleshooting section, where the live diagnostics can check the specifics of your install.
My shortcut does nothing
- Page keys need tab focus. Alt+1 and Alt+3 are
page-level shortcuts that only fire when the Twitch tab and its page body are focused. If your cursor
is in the address bar or developer tools, the page never receives the keystroke.
- Browser command conflicts. Alt+Shift+S and
Alt+2 are registered with the browser. Another extension or your operating
system may have claimed the same combination.
- Active text inputs. While you are typing in a chat box, a search bar or a filter input, the
WASD navigation keys and overlay shortcuts are suppressed so you can type normally.
Fix
Click directly on the Twitch video or page to focus the tab, or open
chrome://extensions/shortcuts to check for a hotkey conflict.
Streamline is not doing anything on this page
- The tab predates the install. Browser extensions cannot inject content scripts into tabs that
were already open before the extension was installed or updated, until the tab is reloaded.
- Unsupported subpages. Some Twitch pages, such as account settings, the Prime Gaming portal
and login frames, restrict extension script injection.
- Interrupted attachment. Rarely, a network interruption or an aggressive ad blocker aborts the
content script before it finishes initialising.
Fix
Reload the Twitch tab with Ctrl+R, Cmd+R on macOS, or
F5.
My rules disappeared
- Sync account state. Signing out of your browser profile or switching sync accounts can make
chrome.storage.sync present an empty state for a while.
- Sync quota. Reaching the 100 KB sync limit can pause cloud synchronisation.
- Update or reinstall. Reinstalling resets local storage while sync storage re-downloads.
Fix
Open the Streamline panel, switch to the Backups tab, and restore a recent entry from Automatic
Backups and Snapshots. Streamline keeps ten rolling snapshots for exactly this.
The overlay will not open, or Twitch changed
- Twitch moved the furniture. Twitch updates its markup, player containers and style classes
often. When the player structure changes, the in-video chat overlay can fail to find its mount point.
- The resilient alternatives still work. Popout chat (Alt+2) and
multiview
docked chat (Ctrl+Shift+D) connect over IRC rather than mounting into
the player, so they keep working when the overlay does not.
Fix
Use popout chat as an immediate stand-in, reload the stream page, and check the store for a
Streamline
update. Compatibility patches ship quickly after a breaking Twitch change.
Keyboard shortcuts
Four shortcuts are registered with the browser. Everything else is a page key that works while the relevant
Streamline surface is open. The complete reference, generated from the code and searchable, is in the
Keyboard shortcuts section of the in-extension guide.

Your rules, backups and export
Everything Streamline knows is in your browser profile and yours to move. The Backups tab of the panel is
the one place to do all of it.
- Restore. Ten rolling snapshots are taken automatically. Pick one and your rules come back.
- Export. Write your rules, settings and layouts out to a file you keep.
- Import. Load that file on another machine, or after a reinstall.
- Erase. Clear everything from the same tab. Uninstalling the extension also deletes it all.
What lives in sync storage versus local storage, and why, is set out in the
privacy policy.
Browser support
Chrome, Edge and Brave get the side panel and the popup with nothing missing. Opera has no side panel API,
so the panel falls back to the popup and every feature is still there. Firefox is packaged as a separate
build, released alongside the Chromium one. The full breakdown is
on the home page.
Report an issue
Twitch changes its markup regularly and Streamline sometimes has to catch up. A report with these four
things in it can usually be fixed without a second exchange.
-
01
Versions
Your browser and its version, and the Streamline version from the panel header.
-
02
Where
The kind of Twitch page: a channel, the directory, a category, search results.
-
03
What happened
What you expected, what you got instead, and whether a reload changes it.
-
04
Diagnostics
The results from the Troubleshooting section of the in-extension guide.
Before you send it
Reload the Twitch tab once. A tab that was open before an extension update cannot run the new content
script until it reloads, which accounts for a good share of reports.
