I see this was already discussed in the past, but the problem seems to persist. While editing a note, pressing Ctrl + right or left arrow will take me to the next or previous note. I regularly do this by mistake, being used to Word etc., and when I get back to the note I actually lose anything I had been typing up to this point without "saving" (for ex. by clicking on another note". I have ended up typing my notes in Word and then importing them to Biblioscape (which I am still evaluating).
