navigation customization

I have managed to change the viewport navigation shortcut too the following.
alt + right mouse to rotate view-port
shift +alt right mouse to pan view-port
They both work but in edit mode the pan view-port ceases to function their must be some conflicting shortcut in edit mode.
Possibly someone can help figure out what is the issue.

Thanks

Those are hotkeys for edgeloop select and edge ring select I believe. Something like that.

Thanks for taking the time to reply.
I will check that out
