TeXworks ⇒ Keyboard functionality

[asafw]

Hello,

I recently reinstalled TexWorks on my Mac (OS X Yosemite) and my keyboard doesn't seem to function the same as it did before. For example, when I use Shift+option+{right arrow} it used (like in all other applications) to bring the cursor to the end of the word, but now this doesn't work (the cursor stays at the beginning of the word); or Shift+option+delete usually deletes the preceding word, but it doesn't work either. Is there a way to restore this option?

Sorry to bother with these petty issues; It's just so inconvenient!

Thanks so much,
Asaf
