What you could do is to replace an accent with an ASCII character. Compare the name of town Český Těšín with its Polish equivalent Czeski Cieszyn (Č → Cz, ě → ie, š → sz). Actually, this is how we got here, 600 years ago Jan Hus (John the Goose) added diacritics to shorten a few diagrams in written language.
I found it hard to switch layouts, I'm using only one with layers. On first layer there are english letters, second layer there are accents (a → á) and some symbols where accent is missing (m → +). On third layer there are arrows on home row and functional keys. Shift without other key is `(`, on second layer `{`. There are some additional keys at the bottom and middle, they cover the rest of symbols. Outliers are mapped to start editor, browser, ctrl+c, ctrl+z, volume, mute, …
I really like having a single layout. I don't like that I'm no longer able to type on QWERTY without looking at keys. On my desktop, I'm 10 % faster, on any other computer I'm 90 % slower. Would I do it again? Probably yes.
I would say there is more than a cheating history and a single game that triggered Magnus. However, most of it has a possible explanation. Like, I would be very nervous if you put me in front of a camera at 19 years. Are these arguments together strong enough? Hard to judge.
* a hair of defined length placed in a bowl or glass of water and vibrations at the resonant frequency of that hair would produce visible ripples around the hair. * distant noise such as car horns honking, bass from a passing vehicle blasting dubstep, construction noise, etc. * laser beam through the window visible only with particular contact lenses * a bone-induction speaker or thumper (vibrating device) embedded in them or replacing a tooth * thumpers that can be put inside the soles of shoes that would not be detectable with a regular metal detector
My impression is that the technology is there. If the incentives are high enough, someone can find the way.
