Can you allow text boxes that need to scroll horizontally, to do so when holding SHIFT and scrolling the mouse wheel?

On the OS X version of SourceTree, the text boxes that exceed with width of its parent container can be scrolled horizontally using the mouse/trackpad.

On Windows, there is no mouse mechanism for doing this (even the "tilt" feature on some mouse's middle buttons does not work). If SHIFT+mouse wheel functionality were added, SourceTree would behave similar to how web browsers handle too-wide-to-fit text boxes.
