When a 4D Form or Form Object is first created it comes with a default set of event handlers turned on, see the image below.



It can be a tedious task to mouse-click on all the unwanted event handers to turn them off. However, there is a quick way to turn them all off at one time. Simply Command/Control click on any checkbox that is turned on and all of them will be turned off. See then image below.



Now, it is very quick task to click on the desired event handlers and be done. In this case the job was done in two mouse-clicks.
