Developer Tools

This functionality will not be implemented in any version of Microsoft Edge.

In Windows Internet Explorer 8, Windows Internet Explorer 9, and Windows Internet Explorer 10, a user can select the browser mode and document mode by using the Developer Tools (F12) in Windows Internet Explorer. These settings remain active for subsequent navigations in the same tab. The following diagram shows how Developer Tools settings impact the browser mode and document mode. This diagram also includes a screen shot of the Document Mode menu in the Developer Tools window.
