Unity lenses

In Unity there is the option to make extra lenses in the Dash. Some are specific for natty narwal and some for Oneiric Ocelot. In This section I only state the lenses that are build for Oneiric Ocelot.



1. Ask Ubuntu
Are you an active user of AskUbuntu? Or that you have plenty of questions about Ubuntu and is always looking to AskUbuntu for answer? Good news for you, the AskUbuntu lens allows you to search the AskUbuntu site right in your desktop (Dash).
Installation:

sudo add-apt-repository ppa:askubuntu-tools/ppa
sudo apt-get update
sudo apt-get install unity-askubuntu-lens
sudo apt-get upgrade


Log out and log in again.

2. Bookmarks lens
Bookmarks Lens allows you to search your web bookmarks directly from the desktop.
Installation

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install bookmarks-lens


Log out and log in again.

3. Gwibber lens
If you have connected your various Twitter, Facebook and identi.ca accounts, you can now search your tweets, status update or message directly from Dash. There are also ways for you to filter results to show only messages, replies, link, images, videos etc.
Installation

sudo apt-get install unity-lens-gwibber

Log out and log in again.

4. Google Books Lens
You can now use the Google Books lens to look for ebooks in Google Books.

sudo add-apt-repository ppa:davidc3/books-lens
sudo apt-get update
sudo apt-get install unity-lens-books


Log out and log in again.

5. Gdocs Unity Lens
Do you always use Google Docs to manage your documents? You can now use the Google Docs lens to search your documents from the desktop.
Installation

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install unity-lens-gdocs


Next, open up the unity-gdocs-lens.py file and scroll down to line 124.
gksu gedit /usr/bin/unity-lens-gdocs.py

Replace GDOC_USERNAME with your Google username and GDOC_PASSWORD with your Google password. Save and close the file.

Lastly, run Unity Gdocs lens:

unity-lens-gdocs.py
setsid unity


Sources: WebUpd8

6. Web Sources Place
Would you like to be able to search the web without having to open a browser? This is what Web Sources Place is about. It allows you to perform a web search and returns a list of sources instead of pages (e.g. a search for a band name might list MySpace, Wikipedia, Amazon and Last.fm as results, but not individual pages thereon).

Installation

sudo add-apt-repository ppa:cscarney/unity-web-place
sudo apt-get update
sudo apt-get install unity-place-websearch


Note: The PPA should work in Oneiric Ocelot, but I couldn't get it to work.
