Description:
The usual convention for vertical scrollbar operation is that left mouse button clicks in a blank area of the scrollbar would scroll the display by one page up or down. And for many Linux applications, a middle mouse button click would jump to the portion of the file that corresponds to the location on the scrollbar where the middle-click occurred.
However, this convention is reversed with the Workbench scrollbars. When I click the left mouse button on a blank area of a vertical scrollbar, such as the editor or results grid, Workbench interprets this as a middle mouse button click and jumps to that position in the file or results grid. If I click the middle-mouse button, I get a page up or page down shift, behaviour that I expect from a left button click.
How to repeat:
Use the editor in Workbench with a file that requires multi-page scrolling. Or generate a result set that would require multi-page scrolling. Try clicking in the scrollbar.
Suggested fix:
Switch the behaviour of the left and middle mouse buttons
