"Use shortcuts" is not working on gitlab.com/help

I want to figure out, what shorcuts GitLab supports now.

1. There is no special icon/link to get shortcuts list quickly. Maybe it's worth to put it somewhere in the left menu?
2. Item Use shortcuts on the page https://gitlab.com/help (right sidebar) is not working:

Uncaught TypeError: Shortcuts.showHelp is not a function   help:380 

# help:380
<li><a onclick="Shortcuts.showHelp(event)" href="#">Use shortcuts</a></li>
