Named event rules actions descriptions for Form design Aid, Report Design Aid?

Hi,

Could someone please tell me where or pages of the manual where i can find.

Once i right click and press in Event rules in Form Design Aid, where can i find the action of all those events, that i will show in the next images that will be highlighted in red, and the same for the Report design Aid.

I think to know this is very important to put logic to your application.
