Vim Ultisnips - How do I move to the next placeholder or tabstop?

Question

I just installed a brand new copy of Macvim and UltiSnips, but I can\'t figure out how to move to the next completions using tabstops and placeholders.

When I press tab,

Answer 1

It looks like jumping to the next tabstop was mapped to control j. I switched it to tab in the ultisnips source.

" The trigger used to jump forward to the next placeholder.
" NOTE: expansion and forward jumping can, but needn't be the same trigger

if !exists("g:UltiSnipsJumpForwardTrigger")
    let g:UltiSnipsJumpForwardTrigger = "<tab>"
endif

Answer 2

I have the following in my vimrc:

" Set ultisnips triggers
let g:UltiSnipsExpandTrigger="<tab>"                                            
let g:UltiSnipsJumpForwardTrigger="<tab>"                                       
let g:UltiSnipsJumpBackwardTrigger="<s-tab>"
