Consistent Vendor/NPC Shortcut interactions

Requesting consistent npc/vendor shortcut interactions
e.g. Vendor = Alt + Click
Sell = Ctrl + Click
Main Mechanic = Ctrl + Alt + Click
2nd Mechanic = Ctrl + Shift + Click


Currently its usually a guess as to which action a shortcut performs when interacting with a npc, especially for the Sell option
e.g.
Jun / Helen= Ctrl + Alt + Click
Act Npcs = Ctrl + Click
Kirac / Dannig (Expedition) = Alt + Click
Faustus / Niko = No Shortcut
