are there keyboard shoetcuts for letters that exist in french but do not appear on the english keyboard?
Depends which OS you use, but yes! http://french.about.com/od/writing/ss/typeaccents.htm
okay, this might sound like I'm being rude but the only way is to copy and paste the letters off google translate(This is what I do), or look at this website: http://tlt.its.psu.edu/suggestions/international/bylanguage/french.html
thanks everyone! i didn't expect so many good answers so quick thing is, i've been wondering if i can get to the letters that appear on screen (when practicing French with Duolingo) without using the mouse. in other words, are there any Duolingo keyboard shortcuts (for the accented vowels) for the lazy who won't want to change their keyboard settings (and who don't want to use the mouse every time an accent is used in a french word)

No, there are none of these.
I'd suggest you to change your keyboard layout to US (International). It is the same as the usual US layout plus some accents. See http://en.wikipedia.org/wiki/Keyboard_layout#US-International
