spark: search hotkey

I use Spark for os hotkeys. To look for the shortcuts I made a small function:

function spark() { `# search for spark shortcuts; no parameter - list all`      |
cat ~/.dotfiles/spark-hotkeys.txt | grep -i --color=never "$1" || cat ~/.dotfiles/spark-hotkeys.txt;
}

The hotkey list is at ~/.dotfiles/spark-hotkeys.txt. This list had to be maintained manually.
