Two keyboard layouts are all you need. I have a Cyrillic and a Latin one. So I can type in Russian and many-many other languages including Estonian. For the later one, I use the omnipotent compose key. The compose key is a key to trigger the insertion of a precomposed character. Shortly, it allows me to type “\u00e4\u00f6\u00fc\u00f5”. Moreover, it simplifies typing “\u0161” in my family name (Ivani\u0161t\u0161ev). Believe me, this is more difficult with the Estonian layout. Also, I can type “\u20ac” sign.<\/p>\n\n\n\n

On Linux (Gnome) you can activate it as: System > Preferences > Keyboard > Layouts > Layout Options > Compose key. Choose the preferred button that will turn on the composition mode. I prefer Caps Lock. On Windows one requires special software. For example, wincompose.<\/p>\n\n\n\n

The life seems so beautiful when everything is set, and the UK layout is set to default.<\/p>\n\n\n\n

Besides, one can enable compose for Greek alphabet by adding to ~\/.XCompose file:<\/p>\n\n\n\n
