The Unity scopes can be used for a whole lot of other purposes besides searching online, and this variety makes them an indispensable and awesome tool.
There are many users out there who still don't like Unity, even three years after it was launched. Canonical made a lot of improvements to the Dash and the scopes, and this shows in the variety of uses that developers dream up every day.
“So here's Unity Keyboard Scope. Typing a character into the dash gives you all the available character variants, like ú and ù for u, for example. Typing word is also possible.”
“You can then double click on the result to copy that character to the clipboard for pasting wherever it is needed, or single click it to show a preview with lots of details about the character, including how to go about typing it without needing the scope,” said the developer, Mark Tully, in a Google+ post.
So far, this scope seems to work only in Ubuntu 13.10 (Saucy Salamander), and the installation can be done very easily with a PPA:
sudo add-apt-repository ppa:scopes-packagers/ppa
sudo apt-get update
sudo apt-get install unity-scope-keyboard
Enjoy this amazing scope, made possible only with Unity.
