I type a lot in Spanish and have a regular 105-key International Keyboard. So I have NO buttons for ñ or other accented letters. However, by setting the keyboard to "US Alternative International" I can easily type many accented letters. Just ' + e = é for instance. This is just like Windows. However, there I was able to type:
SHIFT + 1 = ! SHIFT + CTRL + 1 = ¡ SHIFT + / = ? SHIFT + CTRL + / = ¿
Very convenient. But I have not been able to find a way to configure this in Ubuntu. I have to go to some site that has these symbols, and then copy-paste. Very inconvenient. Anybody any idea?
