1: Use ** as a wildcard to descend into directories:

$ ls **/*.pyc
foo.pyc bar.pyc lib/wibble.pyc
$ rm **/*.pyc
$ ls **/*.pyc

2: Use patterns in file globs:

$ ls *.(py|sh)

3: Use glob modifiers, e.g. (@) restricts glob to matching symlinks

 $ ls -l *(@)

4: Use tab completion everywhere! e.g. using man…

 $ man zsh[TAB]

5: …for completing command options…

 $ python -[TAB]

6: …for kill

 $ kill Dock[TAB]

7: Navigate the tab completion options with your cursor keys

 $ man zsh[TAB][DOWN][RIGHT][LEFT][UP]

8: Auto-correct your typos

 $ pythn -V
 zsh: correct 'pythn' to 'python' [nyae]? y
 Python 2.7.1

9: Use r to repeat the last command – with substitutions!

 $ touch foo.htm bar.htm
 $ mv foo.htm foo.html
 $ r foo=bar
 mv bar.htm bar.html

10: Highly customisable prompt, including RPROMPT to set a prompt on the right hand side

$ RPROMPT="%t"
