Algebraic Programming Language APL

[Thomas Okken]

If your foreign-language needs aren't too demanding, you may also be able to get by with vanilla Windows. My setup is to install the standard ENG/US and ENG/INTL keymaps ("English (United States) / US keyboard" and "English (United States) / United States-International keyboard", respectively); I use ENG/US most of the time, and switch to ENG/INTL (using the Win+Space shortcut to switch back and forth) to write German or whatever else needs accents. The INTL layout uses dead keys for accents, so there's no need to memorize Alt-XXXX codes.
