>the trouble to manage different keyboard layouts in their head There are two main ways to type in Bulgarian on a PC: BDS - the National standard and Phonetic - a transliteration of Bulgarian (Cyrillic) letters into English ones. I've always hated the Phonetic as its even worse than QWERTY. In high-school I forced myself to touch-type BDS so I can use it even on keyboards that don't have it. So when I heard about Dvorak in the university, I immediately decided to learn it since I already had two layouts in my muscle memory, a third one wouldn't be a problem. Initially I was using a Dwerty layout - a Dvorak when typing, a QWERTY when issuing commands (Ctrl+C, Ctrl+V), but since it was incompatible with Windows 8 I've abandoned it and am currently running on pure Dvorak. I think an affinity towards foreign languages helps a lot, but have no research to back it up [besides Bulgarian I learned French (age 5 - 14), German in high school (age 14-19) and English (age 10-19) and recently (26) some Swedish].
