UKismetInputLibrary::InputEvent_IsControlDown

function Engine Blueprint Since unknown

#include "Kismet/KismetInputLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Returns true if either the left or right Control key was held down when this input event occurred.

Caveats & Gotchas

• Reflects modifier state at the moment the event fired, not a live poll of current key state.
• On macOS this checks the physical Control key, not Command — use InputEvent_IsCommandDown for the Mac equivalent of a typical Ctrl shortcut.
