What's the shortcut for mesh menu? I'm referring this menu:



It's weird that Face, Edge, Vertex and even Add menu all have their own shortcuts, but Mesh doesn't have one. I searched "Mesh" in preference, but even weirder yet, that "Mesh" there is actually "Add" menu.
If you are referring to selecting a vert, edge, or face (by way of the 1, 2, or 3 keys respectively), the key you would use for selecting the entire mesh is l (short for "linked"). This will select the entire mesh that is connected to whatever your mouse is hovering over.
