Hi,

I just want to share some of the tips on reading Email in BB, which I have gone through while reading an article.

1. “T” - pressing the letter T when reading an email, jumps to the top of the email,
2. “B” - pressing the letter B when reading an email, jumps to the bottom of the email,
3. “Space” - pressing the Space bar jumps down one screen in the email,
4. “Shift + Space” - pressing Shift and Space jumps up one screen in the email,
5. “N” - pressing the letter N jumps to the next email,
6. “P” - pressing the letter P jumps to previous email.

Thanks for the tips.

There a bunch of them here:
