How to display stuff in the new Postbit ?

[discover_xs]

Ok so by putting this it works
<li><label>TEXT:</label> <span>VAR</span></li>

but what are the variables

for reputation {vb:raw user.reputation}
does display a number but not the reputation of the user.
Instead it shows the reputation of the user you are currently logged in.

and how to display content from custom field i created?
{vb:raw post['field5']}

where can i see all the vb:raw
options

thank you
