Using Safari v1.3.2 on Max OSX 10.3.9, it appears that code snippets do not work on a new line or when the cursor is not first placed within the text editing area.
1. Without placing the cursor, click on either code snippet - nothing happens.
2. Reload the page.
3. Place the cursor right at the new line after the table, click on either code snippet - nothing happens.
4. Place the cursor "inline" with the text, code snippets work fine.
5. Reload the page.
6. Click on the button for a "blank" page (next to the floppy icon).
7. Without placing the cursor, click on either code snippet - nothing happens.
