How to disable confirmation dialogs for simple operations I have just started using Blender (for video editing), and I have run into one thing that just drives me crazy. 

Whenever I try to do even the most trivial operation, there is a popup asking to confirm that I want to do it. There is no purpose for this, as there is an undo feature, and it is a constant annoyance.

Is it possible to disable this feature? If so, how?
