Changing the "Pan View" Keybind works in Object Mode, Not Sculpt Mode I know I sound crazy but try it. Doing this works perfectly in Object mode, but not in Sculpt Mode. 

To reproduce: 


Change the Pan View keybind from Shift + Middle Mouse to Shift + Left Mouse button. 
Open Sculpt Mode and try Panning the View, panning the view will work in object mode, but not Sculpt Mode. 


Some notes: 


Right Mouse won't work either in sculpt mode, middle mouse is the only key blender will accept to pan the camera.
Alt + Left Mouse will work, but I need it to be Shift + Left Mouse. 
I have looked through the keymap window for conflicting actions that use the same input, but couldn't find any. 


I am just trying to setup sculpting for my iPad using the apple pencil, since the pencil doesn't have a "right mouse button" or "middle mouse button". If i can just fix this problem I will be home-free and able to sculpt on the iPad with blender.
Yes,it can be done. But probably what prevents you to do so is: there's already another "shortcut" using the same combination in Sculpt, by default.

if you search for "sculpt" in preferences, you'll see that there are three different mouse/keyboard combinations to do the "sculpt" action, including this:



you can remove it by clicking on the "x" icon right of it, getting this:



then, if you set you desired "pan" shortcut in the "sculpt" editor section from the default:



to:



you should be able to "pan" the sculpt view with your preferred combination, like I was able to do here:



By the way, remember to save your preferences to keep this configuration or it would reset at next start. You can also reset to factory settings in the same menu.
