There are a select few hotkeys in the Product manager, but they are both quite useful. You can instantly open the Product Tree Manager for a selected product and you can go to the Inventory module to see what quantity you have on hand.
CTRL + E = Launch the Product Tree Manager
CTRL + U = View the inventory for the current part in the Inventory module
