What each shortcut does
Activate ZetaMarker
Injects the highlighter on the current tab. If no highlights exist yet, a toast says ZetaMarker is active. Select text to highlight.
Does not work on unsupported pages — see Google Drive and Google Docs.
Toggle sidebar
Opens or closes the highlights sidebar. See Open the sidebar.
Cycle theme
Rotates System → Light → Dark → System. A short toast shows the current theme (Theme: Light, etc.).
Theme cycling is disabled on Google Drive and Google Docs tabs (no content script there).
Open in dashboard
Opens the current page in the web app when signed in and synced. See Open a page in the dashboard.
Customize shortcuts
- Open the sidebar and click Shortcuts at the bottom, or go to
chrome://extensions/shortcuts. - Find ZetaMarker and assign your preferred keys.
If the link fails, open chrome://extensions/shortcuts manually — the extension shows Could not open keyboard shortcuts. Open chrome://extensions/shortcuts in your browser.
