Under Linux/KDE, I can set (like all OS) the amount of scrolling when the mouse wheel is moved.
But like the double-click speed, IDEA does not take into account the KDE settings.
And the default amount of scrolling in the IDEA editor is too small for me.
For the double-click, there is a workaround (http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5076635) :
add <*.multiClickTime: xxx> in the .Xdefaults.
But does someone know a workaround for the amount of scrolling ?
