Ctrl + 1,2,3... let's switch between tabs. Do you know the equivalent? I'm going to try using it for a while if you say you can run that much tabs and it still runs smoothly. I usually have 40+ tabs open at all times.
CTRL+# are reserved for websites stored in SpeedDial. But maybe [2] helps you. I doubt that any experienced Opera user would require such a feature, because the more fluent you become with the UI the more often you swap tabs around. Instead I stored sites into the SpeedDial that I visit regularly, e.g. CTRL+7 is HN :)

2. While a couple of hundred megabytes is usually a small portion of the total RAM, it could be a critical share of the free RAM, and this is what matters.

This memory bloat is why I switched back to Firefox. After reading this article I fired up Chrome and it loaded about 20 tabs, then a message popped up: Close programs to prevent information loss. Your computer is low on memory.
Looking at the old browser comparisons on Toms, I can see that Chrome's memory has ballooned from 991MB in Chrome 13 to 1619MB in Chrome 23. This is a real problem. I wish Google would return to it's roots of making a lean responsive browser.
