New shortcuts can be added in the preferences Edit > Preferences > Keymap.
With the keymap tab open, navigate to the Window category of shortcuts. Click the Add New button to create a new shortcut. The operator for reloading scripts is bpy.ops.script.reload() therefore the identifier for the shortcut is script.reload. Click on the shortcut field and press ...
not the best answer yet,
but you could try with these commands,
from the script-editor or console-window:
# (replace module name !) - first disable ...
# ... then re-enable
If you right-click that dropdown you can assign a shortcut key, but personally I don't use this feature very often, so I've never set one.
The usual way is to use the Z key to change the viewport rendering mode (note this is for all objects in the viewport). You can also use the buttons in the top right of the viewport.
It occurred to me I was trying to mimic the Tab-Key. So I looked that up in the Keymap. Then just did the same thing, but for Vertex Painting instead of Editing.
Preferences > Keymap > 3D View > Object Non-modal > Add New
Assign V-Key binding

Note: In Vertex Paint mode, 'V' is ...
I landed here when I could not find a solution. My 3d viewport allowed me to rotate around the object but panning was not possible anymore (and it worked before in the same scene).
None of the answers here worked for me. I found a simple solution for my case:
add another view panel (or select an existing one around in the UI)

For example, when you press Alt + P, if your mouse is in a 3D View window, ...
Just go to File menu in blender > Defaults > Load Factory Settings
This Can Work For You But if This Does Not Works then I have Another Idea for you if you are having windows operating system
you should uninstall blender first then before reinstalling it you should go to your c drive or the drive where your operating system is installed then let us suppose ...
By default, Blender 2.8 is configured so that pressing the middle mouse button while dragging the axis around activates the Axis Snap which is used for looking around the view-port.
A way to browse around a scene if you will; seems to be the default most requested operation on new installs.
Under the File > User Preferences > Keymap look for the Animation entry.
There should be a Change Frame entry. Change it to watever you like, in this case I'd advise something like Tweak - Right.
You may additionally have to change the context menu to open on Right - Mouse - Release event instead.
