I'm surprised no-one mentioned Source Insight - it's by far the best editor I've used for truly large C/C++ code-bases - doing symbol lookups almost instantly on a source tree eating up several GBs on the drive was extremely impressive when I was introduced to the software in 2004 (admittedly, the rest of the world has caught up on this one), but what made it great is the pervasiveness of using that capability - there is a separate window which shows the context of the symbol your cursor is currently on, instantly updating when the cursor moves, giving you for every symbol its context at a glance. That alone is so useful I miss it still (MSVC has had the almost equivalent 'code definition' pane for a while, but it's so slow to update it's still effectively useless). Also, to this day it seems like the only code editor that I've seen which doesn't use monospaced fonts, and better yet, utilizes that properly (for example, parentheses vary slightly in size according to nesting level, so it's easy to see at a glance which parentheses match).
