What hotkeys and shortcuts are available in Grasshopper?

Menu shortcuts are customizable, but there are a some special keys and mouse-button combinations that trigger specific functions in the Grasshopper canvas.

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
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

Thanks! Useful to link in class ;)

"LMB+Drag+RMB": Awesome and fast! The same combination with Crtl OR Shift add or removes wires!

Although not specific to canvas, I think it should be mentioned that LMB+shift clicking on the toolbar buttons allow you to select several components before placing them in the canvas. You can then place them one by one by LMB clicking on the canvas or place them all at the same time by LMB+shift clicking on the canvas.

David, could you make a similar post for search shortcuts?

(like typing "//text" creates a panel component with "text" written on it, and so on).

You can personalize shortcuts with RMB over components in toolbar :) It's like alias translated to GH.

Nice Tip Vicente!

Did the LMB+Drag+Alt = copy function disappear for 0.9.0056? Or is there a preference setting I'm not aware of?

Best regards Morten

Yes. It was decided that it wasn't necessary any more....

Only joking! The simple explanation is that Rhino is "swallowing" all ALT button instances so they are not getting through to GH anymore. McNeel are aware and are looking into it.
