In this particular case I am referring to Treating independent code as a function in IDA Pro (and I don't mean to make this a pillory at all!)
Original (full) answer as of this writing:
This is probably off-topic but it sounds like what you need is node groups.
On other SE sites I have often found moderators and other community members pointing out that external sources should be quoted with there most vital statements. This is what I did on Igor's answer, too. Likely reasoning behind this is that if the external link goes stale, the person trying to locate the new location of that information will have it more easy to find what is needed.
You could arguably take at least two sides:
- this is redundant
- essential parts have to be quoted to provide context
Which is it for this SE site?
