Using screenROCK is easy. This page tells you everything you need to know to get the most out of creating, annotating and sharing your videos.
You're not currently using Chrome. Chrome extensions can be installed only in the Chrome web browser; please revisit this page in Chrome.
Installing the extension is a breeze! Just click here to be taken to screenROCK's page in the Google Chrome Web Store. When you get there, just hit the "Add to Chrome" button (shown right).
That will bring up a pop-up box asking you to confirm the installation. (Don't worry; screenROCK is perfectly safe to install.)
Once installed, you may need to click the extensions puzzle piece 
in the Chrome address bar to pin to the screenROCK red cicrle button 
to the address bar, then it will appear permanently in the top right of the Chrome browser. It's that we'll click to start screenROCK...
and select what you want to record.To get started with screenROCK simply click its red circle button in the top right of the Chrome browser.
This will bring up the pop-under window shown to the right. The first time you do this you'll be prompted to login. You can create a free account here.
Once you've logged in, you'll see the pre-recording options shown to the right. Choose whether to record screen or webcam, and whether to include audio from your microphone too.
When ready, hit "Start recording". The first time you do this, Chrome will ask you to confirm that you're happy to share access to your screen/camera/microphone. Once you consent, recording will begin, preceded by a short countdown. (You can turn off the countdown in preferences.)
If you chose to record your screen, you'll be able to annotate the screen...
While you're recording, the screenROCK recording toolbox will appear in the bottom right of the screen.
If you're recording screen, it will look as shown in the top image; if you're recording webcam, a simpler version will show, as in the lower image.
One of screenROCK's coolest features is the ability to annotate the screen while recording screen. To do so, use the annotation tools shown in the top image. These are as follows:
The draw tool - allows you to draw freely on the page like a canvas
The arrow tool - allows you to draw an arrow 
The rectangle tool - allows you to draw a rectangle
The text tool - allows you to add and write text on the pageYou can also change the colour and stroke thickness of anything you draw/write with the picker tools:
The colour picker - use this set the active colour
The thickness picker - use this to set the active stroke thicknessSetting the active colour or thickness affects any currently selected item(s) you previously added. To select an item, click it; it will turn lime green, denoting that it is now selected. To deselect items, click an empty area of the page that you haven't added any items to.
To wipe the canvas of all items you've added, use the dustbin icon 
.
One thing that's important to understand when recording screen is that, by default, the page is in Page + canvas mode.
This means an invisible canvas sits atop the page, on which you can draw and add shapes.
Note, however, that in this mode you cannot interact with the page, e.g. click links, select text etc.
You can interact with the page by changing the screen mode to Just page. In this mode, the canvas (and all items you've added) will disappear, leaving only the page. You're now free to click links or interact with the page in any other way.
The final mode, Just canvas, does the opposite - it hides the page and leaves only the canvas and your drawn items. This means you can use screenROCK as an instant whiteboard!
Another cool feature available to you while recording screen is Stamps. Stamps are pre-made text items you can specify in your screenROCK account which you can then add to the page without having to type them out each time.
For example, if you're a teacher using screenROCK to mark students' homework, it would be annoying to have to constantly type "spelling" each time a student misspells. Instead, we can create a Stamp. Here's how:
Once you've made your masterpiece, stop recording by clicking the red "Stop" button in the recording toolbox
A pop-up box will appear (shown right) allowing you to preview your video before deciding to save or discard it.
To save it, first give it a title. The default title is taken from the current web page's title.
A third option allows you to download the physical video file rather than saving to screenROCK's servers; this can be useful if you plan to upload it to YouTube or embed it into a PowerPoint presentation, for example.
On saving your video, the upload process will begin. A progress bar will keep you informed as to how this is going, and once done you'll be given a unique link to your video which you can share with colleagues and friends.
You can also access all previously-saved videos from your Videos area.
You can set certain global preferences within the screenROCK Chrome extension. To do so, start screenROCK and click the cog icon next to the icon of an exit door 
at the top of the chrome button bar to access the preferences area.
The available preferences you can adjust are:
