I can't scale in 2 direction (axis) using 3d manipulator after modifying hotkey

I changed a lot my hotkey setting . I change most of blender hotkey out of blender standard key to match maya//houdini and maya and at this point, i’ve just realized i can’t do 2 axis scaling anymore. I mean shift drag the z axis (3d anipulator) , won’t scale in XY anymore. How can i get this back. This feature will work agai if i reset the hotkey, but i don’t want to reset it because i’ve made a lot of custom key. Anyone can help ?

i’m using 2.79. Btw this feature does not working in 2.8 .
