Thanks for the help, I still have some issues.
I cannot make the first mapping work properly when called from the function, so I cannot make the hole thing work.

Right now just for the first mapping the function looks like:

function! SelectImapOrUlti()
let save_cursor = getpos(".")
execute "normal \<Plug>IMAP_JumpForward"
return ''
endfunction

imap <c-l> <c-r>=SelectImapOrUlti()<cr>
imap <silent> <NL> <Plug>IMAP_JumpForward

So when writing latex if I have a word in the text like this <+text+> and I hit <c-j> the text shows up as selected and I can backspace and delete it; however if I use the the mapping with the function the cursor is placed on the last +> marker, but the word is not selected.

Any idea how to make this?

Thanks!
