The "textivate>>" button is where the magic happens :0)
You can click on it at any time to have a look at the range of activities that are available based on the information (text, matching items, parallel texts etc) that is in the tabs and text boxes on the textivate home page.
Simply click the "textivate>>" button (the one at the bottom right) and textivate will take you to a menu screen, like the one below:
From the menu screen, you can try out the many textivate activities using the activity menu bar on the left.
(Try it for your self: follow this link and click on the "textivate>>" button to see a menu screen based on a sample English text.)
Click on the "<<Back to textivate home page" button (at the bottom right) to go back to the home page, where you will be able to make changes to your resource, upload it, or start a new resource.
If you want to share your resource with others, such as your students, you'll need to upload it first. To do this, use the "Upload" icon (the up-arrow in the cloud) which appears beneath the text boxes.
If you want to make a new resource, click on the "New resource" icon (the blank page), which also appears beneath the text boxes. Clicking this removes all of the information from the text boxes and tabs on the home page, leaving you with a clean slate.
