For several months now, I've been plagued by unexpected language changes while I'm typing. I'll type one character, maybe a quote or a question mark, and I'll get a really strange character instead, say a capital E with an accent on it. I came to realize that it was the language settings, and I keep the language bar on my toolbar so I can flip back to English whenever this strange thing happens. But I didn't know why it was happening, and I found stopping what I was doing to mouse over to the bar and click back to the language I wanted very frustrating.
Well, now I know what was going on! ALT-SHIFT rotates through the languages. I'm a huge ALT-TAB user, and I ALT-SHIFT-TAB when I need to cycle backwards through that list. I also use a fair amount of other ALT-things, like ALT-A to bring up the favourites menu in IE, then arrow keys to choose an item. I really prefer the keyboard to the mouse. Well I guess every once in a while an ALT-SHIFT gets through to the language bar and flips my language. So now when I go to type a URL and see ццц I can quickly make it right.
