How do I turn on, or find, a keyboard function for espanol? Without it, there are no accents
If you're using the website version of Duolingo, there should be little grey bubbles with accents on them. These are not very convenient, but they work.
If you would prefer to make your keyboard like a keyboard in Spanish speaking countries, there is a bit about that in the unofficial Duolingo wiki. Click here and find the section "Is there an easier way to type accented and special characters than using the clickable buttons?" The answer to using a different layout is here. I would recommend using the US International Keyboard Layout.
If you are using a smartphone then it's easy. The standard android keyboard has all the accents within easy reach. You can download it from the Play store. I can even long-press my space bar to quickly switch to a Spanish keyboard. An example: you can press and hold the "?123" key on the left-bottom of the android keyboard and then slide your finger to the "?" key and hold it until it suggests "¿". Then you lift your finger and voilá, there you have it. For all the accented vowels just press and hold the relevant key until the accented versions pop up, and press and hold the "n" for "ñ". If you are not using a smartphone or android then it is not so easy.
As long as you used "bicycle" that ought to be fine. But "he is able to use the bike" could be mistaken for "él puede usar la moto," where "la moto" (bike) is short for "motocicleta" instead of "la bici" (bike) for "bicicleta". But your "he is able to use" is 100%
