Working with Unicode symbols

Unicode

In Calculate Linux, simply hit Caps Lock to switch between the Cyrillic and the Latin (English, by default) keyboard layouts. If the Cyrillic layout is on, the Scroll Lock indicator is on too. To enter additional symbols, such as currency signs, fractions, etc., the Compose button (rightAlt Gr) is used, known as Super in Xorg.

Below are examples of some Compose key combinations. The keys must be pressed one after another. Whenever the Russian keyboard is used, the letter is labelled as "(ru)".
