Pin nodes to numbered slots to compare up to nine outputs side by side in the Preview grid.

Shortcut	Action
1-9	Pin the node under the cursor to that Viewer Slot
Shift+1-9	Solo that Viewer Slot
Shift+0	Make a Viewer Slot follow the current selection

Preview Manipulators

These modifiers apply while dragging a manipulator handle in the Preview panel (Transform, Crop, Shape, Gradient, Corner Pin, Mesh Warp, Text, Scatter, and others).

Modifier	Action
Hold Shift	Constrain the drag: lock a move to one axis, keep proportions while scaling, or snap rotation to 15° steps
Hold Ctrl	Snap the handle onto the image frame’s edges, corners, center, and (optionally) thirds

Manipulator snapping is configured under View > Manipulator Snapping (Enabled is on by default; Snap to Thirds is off by default).

Paint Node

These shortcuts are active when a Paint node is selected.

Shortcut	Action
B	Brush tool
E	Eraser tool
I	Eyedropper tool
C	Clone Stamp tool
[ / ]	Decrease / increase brush size (auto-repeats when held)
Shift+[ / Shift+]	Decrease / increase brush hardness
Hold Shift while painting	Constrain to a straight horizontal or vertical stroke (also on Mask Paint)

Trackpad (macOS)

Gesture	Action
Pinch to zoom	Zoom the node graph or image preview
Two-finger scroll	Pan the node graph or image preview

Curves Editor

These shortcuts are active when editing a Curves node in the Parameters panel.

Shortcut	Action
Ctrl+click	Add a control point
Alt+click	Remove a control point

Dialogs

Pop-up dialogs are keyboard-navigable. When a dialog opens, its safe action is preselected as the default button and outlined.

Shortcut	Action
Enter or Space	Activate the default (safe) button
Left / Right / Tab	Move the selection between buttons
Escape	Dismiss the dialog (cancel)

The default never lands on a destructive action: Unsaved Changes defaults to Save, and an export name collision defaults to Add Suffix. Sign-in code and feedback fields take focus automatically when their dialog opens, and a valid sign-in code submits on Enter.

Tips

• Context-sensitive shortcuts: keys like G, L, D, and F do different things depending on whether the cursor is over the canvas or the preview panel. L toggles the preview lock from either location.
• Clipboard image paste: copying an image in any application and pressing Ctrl+V on the canvas automatically creates an Image In node with the clipboard contents.
• Wire cutting: hold Y and drag a line across any wires to disconnect them in one sweep.
