In order to type Ó, ö, etc, with the Enlgish keyboard, need to configure the compose key in Linux.


After this, Press "Left Window Key > " > a "  will show  ä with using only English keyboard in Linux. 

Here is some example list:

Composition key + , > c      : ç
Composition key + " > o{a,u} : ö{ä,ü}
Composition key + a > a      : å
Composition key + e > =      : €
Composition key + / > u      : µ
Composition key + s > s      : ß
