Is there a spot on this website that shows the keyboard shortcuts?
I have found that if you are on a question that contains checkboxes, you can press 1, 2, or 3 to check the appropriate box and press the enter key to "check" and "continue"
This is a link to a post where someone took a screen shot of that link that is no longer accessible. :
In windows, install the U.S. International keyboard. You can switch between keyboards with WINDOWS+SPACE. Then, for example, to type è on the international keyboard, you'd type ~, e. It takes a bit of getting used to, since to type a ' you need to hit the ' and then the space bar etc, but once you get used to it, it's almost as nice as the Mac shortcut keys. Almost. ;)
On a mac you use the alt/option key. Option+e creates this accent: ´ and then if you want a certain letter under that, you just type it next so ´becomes é or á. Option+u for ¨/ü/ö/ï etc. Just try option + something till you find the write letter to create the needed diacritical mark.
I recommend switching keyboard layouts. On a mac, there's even a keyboard viewer. http://dl-web.dropbox.com/u/29440342/screenshots/VRTHHJ-2012.12.15-14.44.png
I'm not sure why this answer was down-voted. On a MacbookPro if one wants an "umlaut" for instance, I would hold down the "u" key for an extended period of time. After that, a horizontally numbered list appears in a dialogue box (in this example there are 5 choices). the "u" with the umlaut is the second choice. Then, I would enter the number "2" in order to indicate that I would like the "ü." The same applies for the esset "ß" the "ñ" or ń. For instance, for accent choices for the "u" i will type in each option in order" û, ü, ù, ú, ū. another popular letter with accents is the "o"--->ô, ö, ò, ó, œ, ø, ō, õ, etc.
The existing keyboard shortcuts are great. A few more would be awesome. I would especially like to see a few more keyboard shortcuts on the main page where I get dropped after completing a lesson. In particular, I would like to see "p" start another practice round and "n" start the next lesson. Just my two cents. Thanks.
The shortcuts list is cleverly hidden from view on the help page, here's the direct link: https://support.duolingo.com/hc/en-us/articles/204642284-How-can-I-navigate-lessons-with-the-keyboard-
I helped myself now and created an Chrome extension, so you can also use the space bar now to activate the microphone (mouse no longer required). https://chrome.google.com/webstore/detail/airport1-duolingo-improve/ldgljcgmfgjjjenhdoklnfciiaklochp
I hit some keys, not sure which, and got a screen during a lesson with the initial teaching lesson. I don't know how I got it, and I couldn't figure out how to get out of it. I ended up starting the lesson all over. Anyone know how to get the teaching points to come up and how to then get out of it?
