Ctrl+\ not working in browser

1Password normally defines Ctrl+\ (hold down the Ctrl key and press the backslash key) as the shortcut for filling the form currently displayed in your browser (or letting you choose a Login, if you have more than one that matches the current URL). If that keystroke isn’t working, please try the following:

  1. On the Browsers tab of 1Password preferences, make sure the extension for your browser is enabled.

  2. On the Logins tab of 1Password preferences, make sure Ctrl+\ is still defined as the shortcut.

  3. In the Windows Internet Options control panel, choose the Programs tab, click the Manage add-ons button, and (in the list of toolbars and extensions) make sure 1Password is enabled.

  4. In the Windows Internet Options control panel, choose the Advanced tab, scroll down to Browsing, and make sure the Enable third-party browser extensions option is enabled.

If that doesn’t help, make sure the extension is enabled within the browser, as well:
