actions and controllers question

----- NOOB ALERT -----

When an action is called within a single controller – see below –
how do i hop to another controller, say to add a link that I want the
user to be able to click to edit or view another table? cuz when i
try link_to 'Edit', action => ??? i can't figure out how to make the
jump.

<%= link_to 'Edit', :action => 'edit', :id => @scoreboard %> |
<%= link_to 'Back', :action => 'list' %>
