[ipywidgets]: changing SelectMultiple behavior

[akhmerov]

Current SelectMultiple has the following UI:

• click: deselect all, select clicked entry
• ctrl+click: toggle selection of clicked entry
• shift+click: select range with start somewhere (?), and end at the clicked entry.

How can I interchange the behavior of click and ctrl+click, so that the click always toggles the entry?

Come to think of it, I don't even need the current click behavior at all. Plus since the idea of the widget is to allow selection of multiple entries, maybe toggle selection should be the default click behavior anyway?

The SelectMultiple is implemented using the standard native listbox control for the platform. The nice thing about this is that it is consistent with every other native listbox control. If we want to experiment with another interaction (and your idea sounds great for some applications), I would suggest that we make a custom control with those behaviors.

Thanks for the clarification.

In the end I will probably follow this solution.
