3x3 convolution kernels with online demo

• Which are the most used 3x3 convolution kernels/matrices?
• Which kernel is used for averaging, applying blur or smooth effect, do sharpening or for the emboss effect?
• Which kernels can be used to detect edges, calculate the gradient or the smoothed gradient?
• Can I try somewhere the two dimensional convolution in an interactive application?
  

The frequently used 3x3 convolution kernels are listed below with some short description. At the end of this post there is an interactive demo, where
