Orca/C2/Internet-basics/English
Internet basics with Orca Hello and welcome to this Tutorial in the Orca series. This time we are going to see how we can open the doors of Internet using Orca. We will use the Firefox web browser along with Orca. This is because Firefox has the best accessibility with any screen reader available. So let's first start Orca by going to the run dialog using alt + f2. Then we will enter orca. Now press Alt + f1 to open the Applications menu. The Firefox web browser is in the Internet menu. So keep pressing the down arrow till you locate the Internet menu. Now press the right arrow to open the sub menu. Now again locate Firefox web browser with the down arrow and hit Enter on it. We will wait for the browser to load the page. There you are, Orca tells us the browser has finished loading page. In my case, it is the Spoken Tutorial Page. And did you hear orca telling us the percentage of activity being completed? The reason is that we have a setting in the speech tab of Orca preferences for this. Press insert plus space to open Orca preferences and in the case of laptop you can use capslock plus space. Now since we are at the general page we will press the right arrow to go to the speech page. Now lets locate the progress bar update option by pressing the tab key. As you can hear its a check box which is checked by default. This is the reason why Orca informed us how much percent of the page was loaded in the browser. Press tab again. You would hear frequency in seconds. This is a setting which tells Orca how often you would like it to announce the progress bar updates if any. It is set to 10 seconds by default. Since we have not made any changes, keep pressing the tab key till you locate the Cancel button and hit Enter Now we are back at our web browser. In Most distros such as Ubuntu, Fedora etc, the default page for Firefox is set to a search engine called Google. However, this is not the case in my machine. If Google was not the default page in your browser then you can still open it. For opening any website, you need to type its web address in the address bar. For this, we press alt + d. Now the focus is in the address bar. Orca responded by saying "Search bookmarks and history", and read the address which is in the field. You can press backspace once to delete the current entry. Now type www.google.com and press Enter. If google was not the default page then Firefox will load it this time. Again you can hear that Orca told us that Firefox has finished loading page for Google. Google is a search engine which we can use to find any information we want to. By default we are put into the search box where we can type any thing that we want to search. So let's search for orca screen reader by typing it into the box like this. Now you can press the Enter key to execute the search. As you heard, orca reads out the information provided by google in our web browser. It told us how many results were fetched and in how much time. Well, now since we have some search results, let's see what we can do with the available data. In the browser, google presents the results in sections called headings. On an ideally formatted web page like this one, information is classified in headings. But apart from headings, a web page also contains links to other places. To move between links we press the tab key. So let's press tab once to see if we have some links around. As you heard, Orca told us that there is a link called "Images". The pattern is that Orca first reads the text and then tells us that its a link. That's why you herd Orca saying "Images link". So we know that there are links on this page. For a blind person, it is always adviced to press the tab key once the page is loaded. This confirms that the page indeed contains links. But what about those headings containing our search results? Ok, let's look at them right now. To move through the headings, you press the 'h' key on the keyboard like this. We heard Orca tell us "search results". Well we also herd Orca saying "hedding level 2". This is the way in which smart web designers format their data. To make things simple, just keep in mind for now that higher the number of the heading, higher is its position in a structure. Even the font size for different heading levels differs. Still confused? Well, just press the 'h' key again and things will become clear. Now we are into the actual results which google fetched for us. This time though, we also herd Orca announcing that the heading level is at 3 and its also a link. So you can easily notice that the search results was at the higher level heading at level 2 and all the results are at heading level 3. wish to confirm again? Ok, to go back one heading, press shift + 'h' like this. There you are. Orca says "search results" which it informs at heading level 2. Press 'h' to move in forward direction as we did before. Now we are on the first result which is actually a link and is shown as heading level 3. You can press the down arrow once to read brief overview of this search result. Since I am curious to know more on this result, I will hit Enter on this link. You can now read the loaded page with similar navigation keys. Press the 'h' key to go to a heading. Now you can also use the say all command you have learned previously in the tutorials for using Orca on the desktop. Just to recap, you can press the num pad plus key on the desktop or Caps Lock plus semi colon on the laptop. As you can hear Orca started to read the entire page. So that's it for this tutorial. We have graduated to a new level of computer usage. So until the next tutorial, this is Sagar and Duhita saying goodbye!
