Greenscreen on/off button Powerpoint

[HenkR]

When working with powerpoint we use a green screen to show a camera recording.
When there is a picture with green in powerpoint this will be filtered out bij the green screen.
Is there a way to simply switch on/off the croma key.
Maybe its possible to put a button on the home screen of OBS

Did you set the Chroma Key filter on the camera source or on the scene?
If it is on the camera it should work fine.
If it is on the scene, every source that is in that scene will respond to the chroma key.
Check the scene filters and if there is a chroma key, remove that filter.
