Keyboard Modifier

Keyboard Modifier

Detects keyboard key press and generates an output.

Method #

This node detects keyboard key presses of a specified key and generates an output for modifiers. Useful for making quick button inputs to test effects.

The Keyboard modifier node only works in Builder and in Standalone executables. When in Builder, the play-head must be playing and the viewport window must be selected by clicking on it.
This node does not function in media servers, as media servers capture all keyboard inputs.

The output is a numeric value that acts upon a connected parameter input of another node, using the operation method selected.


These properties control the core behaviours of the node.
