Start case:
1. Create a document that starts with {{echo|<div>foo</div>}} followed by some more content
2. Put the cursor on the paragraph below the template
3. Press left arrow until you're selecting the template
4. Press left arrow; the cursor is now in the block slug
5. Press left arrow; the cursor is now on the template
6. Go to step 4

End case:

1. Create a document that ends with <references /> preceded by some content
2. Put the cursor in the paragraph above the reflist
3. Press right arrow until you're at the end of this paragraph
4. Press right arrow; the cursor is now on the reflist
5. Press right arrow; the cursor is now in the block slug
6. Press right arrow; the cursor is now before the reflist 
7. Go to step 4

Note how the end case differs from the start case in that the loop is 3 keypresses long rather than 2.
