fancy-ctrl-z

Allows pressing Ctrl-Z again to switch back to a background job.

To use it, add fancy-ctrl-z to the plugins array in your zshrc file:

plugins=(... fancy-ctrl-z)

Motivation

I frequently need to execute random commands in my shell. To achieve it I pause
Vim by pressing Ctrl-z, type command and press fg to switch back to Vim.
The fg part really hurts me. I just wanted to hit Ctrl-z once again to get back
to Vim. I could not find a solution, so I developed one on my own that
works wonderfully with ZSH.
