Hi,
right_Alt+s is not only a problem for Slavonic languages, it is also a problem for the US_international keyboard:
I and many (bi- and multilingual) users use this keyboard becasue one can write in many different languages without switching the keyboard, e.g. to write à, ü, ç and... the German ß, which is right_Alt+s. I cannot use the windows version of Evernote anymore because I also need to write letters in German and there are so many ß...
SOLUTION until the Evernote team solves the issue: I simply use the web version.
A suggestion to the evernote team:
I can understand that you like to keep options to a minimum to have an easy & lean GUI. I think you are doing very well with his and I am a very happy user of Evernote. However, I find that your "Options" tab is too small. It is respectful practice for Windows programmers to give users the freedom in 'Options' to change the shortcuts, becasue shortcuts can interfere with other programs. Please respect this, too, this is very basic.
