suggestion for code preview

[GoogleCodeExporter]

"middle-clicking the scrollbar shows a preview of the code around the clicked 
line" is not very convenient, because when I found the code, I should left-
click the mouse.

I hope I could press the left button and hold, then the code preview show. If
I release the button, it go to the line. If I release the button outside the 
bar, code navigation is invalid.

But then it wouldn't work as a scrollbar anymore. If you move the mouse with 
the left
button held, the expected behavior is to scroll the text window. How would you 
tell
if the user meant to scroll, or display the preview? And what's wrong with
middle-click for preview?

Being able to lock the preview would be nice. Like shift+middle click locks, 
middle 
click again unlocks.
