Thank you Wolfgang for your answer.
I have create some commands in minibar were i could choose or the part,or the assembly or the faces,as showed here:
Choosing a part i would like with a command (icon) to choose is "father" (or parent as you right says) were this part is contained and clicking again the icon were is father is contained.
The same as the command "probe selection" that show me were select a part you can see were it's contained in the tree model.
For my way to work i need to alternatively to click the icon for select a part and clicking that ("missing") icon to select the assembly were the part is contained and clicking again to select the assembly were the assembly is contained.
In the previous version there was something like this
I have not understand "adapt your start shortcut and append the parameter "-v" to the command"
Thank you again for your help
