Zeshan Ahmer shared a screen shot on Twitter of Google testing showing "All" instead of the "Web" navigation filter link.
Typically when you do a search at Google you see the default option set to "Web" at the top, under the search box. You can often toggle to filter for News, Images, Videos, Shopping, etc. But Google is trying out showing "All" instead of "Web" at least in India.
Here is a picture from Zeshan Ahmer:
I am not able to replicate this myself on Google.com or Google.co.in, but it wouldn't surprise me if Google was testing this.
