Menu shortcuts are customizable, but there are a some special keys and mouse-button combinations that trigger specific functions in the Grasshopper canvas.
GH选项里可以修改一部分快捷键，下面是一些特别的快捷键用法（转自David Rutten）（LMB是鼠标左键，RMB是右键，MMB是中键）；
Always:
RMB+Drag = Pan left/right/up/down
RMB+Ctrl+Drag = Zoom in/out
Scroll Wheel = Zoom in/out
MMB+Click = Wheel menu
Spacebar = Wheel menu
LMB+Alt+Drag = Split objects (aka 'The Moses Tool')
While over an empty canvas spot:
LMB+Drag = selection rectangle
LMB+Shift+Drag = addition selection rectangle
LMB+Ctrl+Drag = removal selection rectangle
RMB+Click = Canvas menu
While over an object:
LMB+Drag = Drag selected objects
LMB+Shift+Drag = Drag selected objects along 45-degree guides
LMB+Drag+Alt = Copy all dragging objects
LMB+Click = Either select one object or do nothing if object is already selected
LMB+Shift+Click = Add an object to the selection
LMB+Ctrl+Click = Remove an object from the selection
LMB+Ctrl+Shift+Click = Toggle the selection state （这个可能大家不知道，我认为非常有用，把一个运算器的某个端口上的所有连线移到另一个运算器上。可不要傻乎乎的一个个重新连线）
LMB+Ctrl+Alt = Info mode
LMB+Ctrl+Shift+Alt = Save info mode as image
RMB+Click = Object context menu
While over an input/output grip:
LMB+Drag = Create a new wire
LMB+Shift+Drag = Create a new wire without erasing old wires
LMB+Ctrl+Drag = Erase an existing wire by tracing over it
LMB+Ctrl+Shift+Drag = Move all existing wires to some other grip
LMB+Drag+RMB = Create a new wire without exiting the wire tool
LMB+Drag+RMB+Shift = Add a wire without exiting the wire tool
LMB+Drag+RMB+Control = Remove a wire without exiting the wire tool
While over a component icon on the toolpanels:
LMB+Shift+Click = Create a component aggregate
