Before I explain how does Dash look like and work, let’s review what you saw last time with one little addition I forgot to mention. I hope you don’t mind.
Ok, last time you learned that you use only applications, and operating system is there to help you to run these applications. Also you have learned what is Ubuntu and how does it look like.
When you visited Ubuntu’s online tour you were able to see Ubuntu’s graphical user interface, (Launcher and Indicators), as shown on figure 1.
One little addition shown on figure 1, forgotten last time, is Ubuntu’s main menu. You can actually see that menu when you drag your mouse up in the left corner. (One little hint: that menu is hidden until you “point” it with a mouse).
After the review what you saw last time let’s start with theme of a day: Dash.
You have probably caught yourself, while surfing on the Internet, writing just a keyword in the web browser’s search box. Right after that, you got some results. Well, Dash is an application that has a similar function, i.e. search function. Same as with web browser which enables you to find some information faster, Dash helps you to find applications/files you have on your computer faster.
To open the Dash you have to left click on a first icon on a Launcher as shown on figure 2., (it has Ubuntu sign on it).
After you clicked on a Dash icon you should see how does Dash look like as shown on figure 3.
Important parts of a Dash on a figure 3, (surrounded with a red line), are:
1. Search box – this is where you type the name of an application or a file you are searching
2. Dash body – here you can actually see what you can find under Dash
3. Dash lenses – they show you where you currently are under Dash – (this part will be explained in more detail later on).
By now you should have a general picture, in your head, about the Dash and its purpose. The last part of this article are Dash lenses.
Dash lenses are there to make your search easier. Thus you have
Applications lens – where you search for applications
Folders/Files lens – where you search for files and folders you have
Music lens – where you search for music file you have
Video lens – where you search for videos you have
If you click on an Application lens you should see that Dash has changed its appearance and it is ready for application search. (See figure 4.)
If you click on a Files/Folders lens you should see that Dash has changed its appearance and it is ready for files/folders search. (See figure 5.)
You probably got the picture how does lens switch work and what does it do. So, as you switch lenses Dash changes its appearance and it is ready for your search request.
In this article you have learned what is Dash and how it functions. In the next article I will explain next crucial part of a Launcher – home folder.
