If you have set up a resource or activity in a block, and wish to move it to a different block, follow this procedure.
In the course page, click the
button.
The method you will use depends on what browser you are
using. In some browsers, you will see a
four-pointed arrow next to each item:

If this is what you see, click the four-pointed arrow next to the item you want to move, drag it into the block where you want to place it, and drop it there. You are done.
In other browsers, you will see a
double-arrow icon next to the name of the resource or
activity:

Suppose you are moving something called “Quiz
1”. Click the
double-arrow icon in that item. You will see a page with
a number of small rectangular boxes with dashed borders,
like this:

Each of these dashed boxes represents someplace you may put your resource or activity. In the picture above, you would click on the first one to place Quiz 1 before the link in the course block; the second box would place it just under the forum link; and so forth.
