IE7 Tabbed Browsing: Nice
I've just started playing with Internet Explorer 7, and I must say that I'm very happy that they've used the hotkeys and conventions that Firefox created rather than inventing their own.
Firefox uses Ctrl-T to create a tab, Ctrl-Tab to switch between tabs, and Ctrl-W to close a tab. The MSN Toolbar tab implementation ignored these and did their own thing, but IE7 works the way Firefox does.
The Firefox way works well - it's nice to see that Microsoft didn't succomb to NIH syndrome.
