The further from the center of the scroll bar, the faster the text will scroll. The closer to the center, the slower it will scroll. When you move over the center it pauses.

Dashing through the snow<br>
In a one horse open sleigh<br>

O'er the fields we go<br>
Laughing all the way<br>
Bells on bob tails ring<br>
Making spirits bright<br>
What fun it is to laugh and sing<br>
A sleighing song tonight<br>
<br>
Oh, jingle bells, jingle bells<br>
Jingle all the way<br>

Oh, what fun it is to ride<br>
In a one horse open sleigh<br>
Jingle bells, jingle bells<br>
Jingle all the way<br>
Oh, what fun it is to ride<br>
In a one horse open sleigh<br>
<br>
A day or two ago<br>
I thought I'd take a ride<br>

And soon Miss Fanny Bright<br>
Was seated by my side<br>
The horse was lean and lank<br>
Misfortune seemed his lot<br>
We got into a drifted bank<br>
And then we got upsot<br>
<br>
Oh, jingle bells, jingle bells<br>
Jingle all the way<br>

Oh, what fun it is to ride<br>
In a one horse open sleigh<br>
Jingle bells, jingle bells<br>
Jingle all the way<br>
Oh, what fun it is to ride<br>
In a one horse open sleigh yeah<br>
<br>
Jingle bells, jingle bells<br>
Jingle all the way<br>

Oh, what fun it is to ride<br>
In a one horse open sleigh<br>
Jingle bells, jingle bells<br>
Jingle all the way<br>
Oh, what fun it is to ride<br>
In a one horse open sleigh
