Shortcuts

Gradient Tools' shortcuts are modal — they work while a painting tool is active. There are no global hotkeys to memorize; the active tool also draws an on-screen HUD with its keys.

While painting (all tools)

Key	Action
F	Invert the gradient (even mid-drag)
Esc	Cancel the current paint
Right-click	Cancel (or, in Path, apply)

Paint (Drag / Freehand)

Input	Action
Click + drag	Set the gradient direction (Drag) or draw the stroke (Freehand)
Release left mouse	Apply

Radial

Input	Action
Click	Set the gradient center
Drag out, then release	Set the radius and apply

Path

Key / input	Action
Click	Place a control point
Backspace	Undo the last point
S	Toggle Bézier smooth mode
Drag a point	Move a control point
Drag a handle (●)	Shape the curve
Alt + drag handle	Free the handle (break the mirror)
Enter / right-click	Apply

Useful Blender keys (not part of the add-on)

Key	Action
N	Toggle the sidebar (where Gradient Tools lives)
Tab	Toggle Edit Mode (needed to select faces)

Tip

You never have to remember these — every active tool shows its own shortcut HUD in the viewport.
