Key callbacks at VisualizerWithEditing

[gdelcacho]

Hi. I am trying to crop a mesh at a VisualizerWithEditing instance (in the selection mode). I would like to override the 'S' callback in order to implement my own saving function (I want to save the cropped mesh with my own default name and without clicking on a save button, just pressing 'S').

Apparently, it is not possible combining both features (manual cropping and key callbacks), but maybe you can give me a similar solution, maybe the GUI has some customizable features I can use.
