On every browse list, you can split the screen into two. At the bottom of the browse list, on the left of the horizontal scroll bar is a vertical bar. This is the split scroll bar.
The Split Scroll bar
If you move your mouse pointer to this split scroll bar, the cursor will change to a double sided arrow. By clicking and holding down the left mouse button, you can drag the split scroll bar anywhere in the browse list. When you release the mouse button, the browse window will be split into two. You will notice that there are now two horizontal scroll bars at the bottom of the browse list.
Asset Browse Window with Split Scrolling
If you move the mouse pointer to the area where the two scroll bars meet, you will find that by clicking and dragging you can reposition the "split" in the list. This feature is very useful if you wanted to examine details that are at opposite ends of the display.
