Hmm... it is unusual that a normal click can also select a range. Usually, one would expect to use SHIFT+CLICK to do so, which you can actually do too. :-D I suppose that behavior originates from that older multi-selection list, where a simple click changes the selection state of a single element.... which is also quite unusual given today's widgets in other GUI frameworks.

Here is what I would expect from a multi-selection list:
- simple click clears and sets the entire selection to a single element
- shift+click adds a range to the selection starting from the current element to the clicked one
- ctrl+click toggles the selection state of a single element
- click-drag drags whatever is currently selected

Best,

I mildly disagree. Dragging *out* would make sense in various ways. To open another browser, for example. To drop into a text view (where I'd quite like to get the method's reference pasted, perhaps with shift held the method source. Right now we get a not very useful 'compiledMethodBunchOfDigits') or a FileBrowser.

I can imagine having a use for a message trace open on several related methods that do not specifically tie together. Maybe #at: & #at:put: would be an example. This would be using a message tracer as a way of gathering methods together as part of thinking about refactorings or extensions.

I'm thinking here of using a messagetrace browser and wanting to add little (pop-up?) notes to remind me of any points I notice as I follow the messages up and down. Why was I looking at this? What is it related to? All that stuff it is so easy to forget a week later when you start climbing back up the rabbit hole you fell into.

I don't want to *edit* the code for this, I want to *annotate* it in the context of the tool I am using.

One might make a plausible argument that this is not a message tracer anymore; whatever. I suggest that it would be a useful tool.
