If you have a mouse with a scroll wheel and are running Java 2 version 1.4, you can use the wheel to scroll up and down in the text area. Various modifier keys change the action of the wheel:

- Shift - scrolls an entire page at a time.
- Control - scrolls a single line at a time.
- Alt - moves the caret up and down instead of scrolling.
- Alt-Shift - extends the selection up and down instead of scrolling.
