I'm using an external US International keyboard. When pressing the quotation mark button, together with Shift (⇧ + ") some special mode enables.
When I type a vowel, the following comes out: ä ë ö ï ÿ This is not my desired output, I wish for "a".
Wikipedia told me this is named Diaeresis:
The diaeresis, also spelled diæresis or dieresis and also known as the tréma or the umlaut, is a diacritical mark that consists of two dots placed over a letter, usually a vowel. When that letter is an i or a j, the diacritic replaces the tittle: ï.
But several internet searches have not yielded any results in how to change this behavior.
How can I change this behavior?
