Keyboard and mouse#

Every shortcut and mouse action the plugin adds, in one place. ComfyUI's own shortcuts (queue, copy and paste, undo, ...) are unchanged. Keys on the canvas act only when no text field has the focus.

Network editor (canvas)#

Input	Action
Tab (pointer over the canvas)	Open the PCG node menu at the pointer, like Houdini's Tab menu. It lists only PCG nodes.
Type in the menu	Search by subsequence: `pe` finds PolyExtrude, `grcr` Group Create.
↑ / ↓, Ctrl+P / Ctrl+N	Move in the list.
Enter	Create the node at the pointer.
Esc, Tab	Close the menu.
Y + left-drag	Cut every wire the drawn line crosses. Esc cancels.
Alt + left-drag on two or more selected nodes	Arrange them in a column (drag vertically) or a row (drag horizontally). Esc cancels.
Shake a node while dragging	Disconnect all its wires.
Press and drag the last third of a wire	Move its input end to another input; dropped on empty canvas it disconnects.
Press and drag the first third of a wire	Pull a new wire from the same input to choose another output.
Shift while dragging a node	Do not snap to wires and neighbours.
Drop a wire on a panel cell	Connect it to that parameter.
Click the blue square above a node	Show the node in the floating 3D panel (display flag). Again: clear it.
Click the grey square, or right-click / Ctrl+click the blue one	Use the node as the template (grey wireframe).
Click a COP node's thumbnail	Next layer (when there are several), otherwise the next display mode.
Shift+click a COP thumbnail	Next display mode: auto, clamp, signed, normalize.
Hover a COP thumbnail	Show the pixel value under the pointer.

Wire style, snapping and the other canvas behaviour are described on Wires.

Parameter panel#

Input	Action
Type a number, Enter	Set the value (replaces any expression, reference or keys).
Type a formula, Enter	Store it as an expression (the field turns cyan).
Esc	Abandon the edit.
↑ / ↓ in a number field	Step the value; Shift ×10, Ctrl ×0.1. In a keyed field this sets a key; fields driven by an expression or reference do not step.
Drag left / right on a number field	Scrub the value; Shift faster, Ctrl slower.
Alt+click a field	Set a keyframe at the current frame. Alt+click the label: key the whole row.
Alt+Shift+click a field	Delete the keyframe at the current frame.
Hold the middle mouse button on an expression or reference	Show its current value.
Click a parameter's label	Toggle that row between expression and value.
Right-click a row or cell	Copy Parameter, Paste Relative References, keyframes, Disconnect, Revert to Defaults ...
`▾` next to a group or attribute field	Pick a name that exists on the upstream geometry.
Tab in a code or multi-line field	Insert 4 spaces (instead of moving the focus).

Ramps

Input	Action
Click an empty spot	Add a key there and keep dragging it.
Drag a key	Move it (left / right = position, up / down = value on a float ramp).
Double-click a colour key	Pick its colour.
Right-click a key, or Delete / Backspace	Remove the selected key (one always remains).
← / →	Select the previous / next key.

Edit Parameter Interface dialog: Esc closes it; Delete removes the selected parameter (when no field is being edited).

3D viewport and floating panel#

Input	Action
Left drag	Tumble.
Middle drag	Track (pan).
Right drag, mouse wheel	Dolly.
Double-click, F / G / H / Home	Frame all.
1 / 2 / 3 / 4	Perspective / top / front / right view (also leave the UV view).
5	UV view on / off. In the UV view: left or middle drag pans, right drag or the wheel zooms (about the pointer), F frames the layout.
Alt or Space + left drag	Tumble, even while a handle or the curve tool is active.

Keys act while the pointer is over the view, also when a toolbar menu of the panel still has focus; only a text box being typed in keeps its keys.

Handles (select a node that has one, see Handles):

Input	Action
T / R / E	Translate / rotate / scale handle.
Drag an arrow / square / centre circle	Move along an axis / in a plane / in the screen plane.
Drag a ring	Rotate.
Drag a scale box / the centre box	Scale along an axis / uniformly.
Ctrl while dragging	Snap: a tenth of the grid unit, 15 degrees, steps of 0.1.

Curve tool (select a Curve node):

Input	Action
Click empty space	Add a point at the end (on the geometry under the pointer, or on the construction plane).
Drag a point	Move it. Shift: snap to the surface; Ctrl: snap to a tenth of the grid unit.
Ctrl+click a segment	Insert a point.
Delete / Backspace over a point	Remove it.
Click the first point	Close the curve.

Playbar#

Shown when the graph has a Frame (PCG) node.

Input	Action
Space	Play / pause.
← / →	Previous / next frame.

These act only when no text field has the focus and no modifier key is held; the keyboard button on the playbar turns them off.

Geometry Spreadsheet#

The mouse wheel scrolls the table (not the canvas); the tabs switch between point, vertex, primitive and detail.
