US International
Keyboard layout

Holding the right Alt Key (Alt Gr) while pressing another key on the US International Keyboard yields the blue characters depicted in the layout below. Shown here is the PC104 (with 104 keys) which will obviously differ slightly with many notebook layouts.

Example 1: to type the Euro sign € hold the Alt Gr and press 5

Example 2: to type a capital C cedilla Ç hold both the Alt Gr and a Shift key and press ,

Type characters that are used less frequently, e.g. currency symbols, typographic marks and accented letters in other languages: French, German, Icelandic, Danish, etc.

Dead keys

There are more than a dozen dead keys on (Kubuntu) Linux and most of these are combinations with Shift and / or Alt Gr.

First press the dead key (combination) then release the dead key (combination), and subsequently type a letter.

Example 1: To type Ô, press Shift + 6, release and type O

Example 2: To type ğ, press Alt Gr + Shift + 9, release and type g

In some cases you can combine two diacritics like in ậ; first press the dead keys for the circumflex and then the dead keys for the underdot (or vice versa).

Pressing a dead key followed by pressing the space bar produces the character denoted by the dead key; e.g. ~ + space results in “~”, see the Tilde row in the table below.
