What is alternative to Unity's lens for Gnome Shell?

Question

Is there any functionality like lens for Gnome shell? or any modified version of Gnome Shell.

Answer 1

I was very happy with gnome-do, but with Ubuntu Quantal I've got some problems with the hotkeys: I had to set the activation hotkey on every new session and it was everyday.

In 2 days I was looking for a solution and found more than that: Meet Synapse – the super fast new GNOME Do replacement

To install it, just the commands above:

sudo add-apt-repository ppa:synapse-core/ppa
sudo apt-get update && sudo apt-get install synapse

Talking about the plugin usage, that @Evandro Silva mentioned, it's possible with Sypase too.

P.S.: You can found more information and some snapshots in the website that I mentioned. I took the commands from there.

Answer 2

I use gnome-do, just search for it on the software center, or use the following command:

sudo apt-get install gnome-do

Like unity lens, you can add plugins to search for more specific things:
