General animate state hotkeys ¶

Hotkey or Interaction	Action
`⌃ Ctrl` + `⇧ Shift`	With multiple controls selected, holding `⌃ Ctrl` + `⇧ Shift` puts the handle in global transform mode.
`C`	Displays a radial menu with the available tool options.
`⇧ Shift` + `F2`	Toggles the display of the HUDs.
`⌃ Ctrl` + `G`	Brings up the settings HUD, which allows you to change various settings for the tools and operations in the animate state.
`G`	Brings up the parameters HUD, which allows you to change the transform component values (translate, rotate, scale) of the selected control, as well as some tool-specific parameters.
`⇧ Shift` + `V`	Toggles the display of the selection sets HUD.
`V`	Brings up a HUD with a filtered list of the selection sets that contain selected controls.
`P`	Brings up the handle parameters window.
drag in empty space	Translates the selected controls.
`Y`	Cycles through the different handle modes for the active handle.
`T`	Changes the active handle to translate mode.
`R`	Changes the active handle to rotate mode.
`E`	Changes the active handle to scale mode.
`M`	Cycles through the different handle alignments for the active handle.
`F`	Frames the selected controls.
`⌃ Ctrl`	Holding `⌃ Ctrl` while moving the different transform handles changes the handle component (translate, rotate, scale) by the step size set in the handle parameters window.
`⇧ Shift` + `'`	Toggles pivot mode on and off.

Unassigned hotkeys ¶

The following actions are available in the animate state, but are not assigned to specific hotkeys:

Action	Description
Hide All Controls	Toggles the visibility of the controls that are currently visible (controls that have the icon displayed beside its name in the selection sets HUD/pane).
Switch Alignment Modes	Switches the handle alignment mode between world and local alignment.
Toggle Handle Visibility	Toggles the visibility of the handle.

Use the hotkey manager to assign actions to a hotkey:

Open up the hotkey manager by selecting Edit ▸ Hotkeys in Houdini.
In the Context list, go to Houdini ▸ Panes ▸ Geometry Viewers ▸ Operations ▸ Modeling (SOP) Operations ▸ apexanimate Operation.
In the Action list, select the action.
In the right pane, double-click .
Type the hotkey you want to assign to the action, or click the key on the virtual keyboard at the bottom of the window.
Click Accept.

Locators ¶

Hotkeys for working with locators.

Hotkey or Interaction	Action
`H`	Creates a new locator at the mouse location. If a control is selected, creates a new locator at the location of the control handle.
`⌃ Ctrl` + `H`	Removes the selected locator.
	Changes the shape of the selected locator.
`⇧ Shift` +	Changes the size of the selected locator.
`G`	Brings up a HUD that allows you to change the color of the locator.

Transient constraints ¶

Hotkeys for working with transient constraints.

Hotkey or Interaction	Action
`A`	Adds a transient constraint.
`⌃ Ctrl` + `A`	Removes a transient constraint.
`⇧ Shift` + `A`	Hold `⇧ Shift` + `A` to adjust the driver object.

Regular constraints ¶

Hotkeys for working with regular constraints.

Hotkey or Interaction	Action
`H`	Adds a constraint.
`⌃ Ctrl` + `H`	Removes a constraint.
`G`	Brings up a HUD with options for baking and turning on/off a constraint.

Dynamic motion ¶

Hotkeys for working with dynamic motion.

Hotkey or Interaction	Action
`H`	Pressing `H` the first time sets the center of mass control. Subsequently pressing `H` sets the start and end of a section of dynamic motion.
`⌃ Ctrl` + `H`	Removes the current section of dynamic motion.
`⇧ Shift` +	Changes the size of the dynamic motion path ticks.
`⌃ Ctrl` +	Changes the size of the dynamic motion path height planes.

Ragdoll ¶

Hotkeys for working with ragdoll.

Hotkey or Interaction	Action
`H`	Starts creating a ragdoll for a character.
`⌃ Ctrl` + `H`	Removes the ragdoll for a character.
`O`	Enters ragdoll pose mode.
`⌃ Ctrl` + `E`	Toggles the active state of the selected collision shape.
	Applies gravity on an object.
