A note about click and control/alt. Now for unix system the command in mac is equivalent to the alt key. Particularry alt + click are catched by the os (to do some fancy windows moves). So what works in mac as command + click is mapped in unix as alt + click. 2013/9/17 Benjamin <benjamin.vanryseghem.pharo@gmail.com>
If you want to react to some selection, you should better use whenSelectedItemChanged: I guess

Ok, I get that. Still, when you create a NewList you have to provide a setIndexSelector, for example in the CategoryWidget I am doing:
categoriesList := NewList on: self getItemsSelector: #getCategories setIndexSelector: #selectedCategoryIndex: getDisplaySelector: #categoryWrapper:.
So, every time you click on the categories list (both selecting multiple categories or not) the CategoryWidget receives the #selectedCategoryIndex: message. The current selectedCategoryIndex: message reads like this:
selectedCategoryIndex: anInteger
| anObject | anObject := self getCategories at: anInteger ifAbsent: [ nil ]. self model selectedCategory: anObject. self changed: #selectedCategoryIndex. self model categorySelectionChanged. self model changed: #currentHistoryIndex.
Also the NewList is in the list of dependents of the CategoryWidget, so it also gets the #update: message Is this right?
