Anyone else having trouble completing a lesson because you can't put accents over letters on your laptop keyboard? I can't access the Greek on my phone, where my keyboard has accent marks...
On my keyboard (which came with Windows), I have to press the ';' key (that's a semicolon, not a Greek question mark) and then the letter in question to get the letter with a tonos. There are various other accents that work in a similar way (most of which are not used in modern Greek).
It has never failed an answer for want of an accent, however, so if you cannot complete a lesson you might be making other errors.
Could it be because I'm not putting an alpha and am instead putting an A? I noticed when I popped into Danish that there are other letter options on the Web Version beneath the answer box that I can click on to help me spell things 'correctly' (like the 'ae' together, for example) that wasn't there for Greek. I'm beginning to wonder how much of this is because it's still in Beta mode? There's absolutely no way I can misspell a four-letter word with only three different letters in it. It's asking me to write, in Greek, what I hear. I try on my English keyboard and it won't let me advance. It says I've gotten it wrong and I look down at the correct answer and go to spell it that EXACT way the next time (minus the alpha, because English keyboard), and I'm still incorrect.
