I agree now that I'm wrong on that.
so I got these from the plugin code:

" Which key to map to Select-Node-and-Shuttle-between-Body/Tree
if !exists('g:voom_return_key')
let g:voom_return_key = '<Return>'
endif

......

exe "nnoremap <buffer><silent> ".g:voom_return_key." :<C-u>call
Voom_TreeSelect(0)<CR>"
exe "vnoremap <buffer><silent> ".g:voom_return_key." <Esc>:<C-u>call
Voom_TreeSelect(0)<CR>"
"exe "vnoremap <buffer><silent> ".g:voom_return_key." <Nop>"
exe "nnoremap <buffer><silent> ".g:voom_tab_key." :<C-u>call
Voom_ToTreeOrBodyWin()<CR>"
exe "vnoremap <buffer><silent> ".g:voom_tab_key." <Esc>:<C-u>call
Voom_ToTreeOrBodyWin()<CR>"
"exe "vnoremap <buffer><silent> ".g:voom_tab_key." <Nop>"

this is a bit complex kind of map... so based on that , how can I make a
jump within my script?
I tried:
exec "<C-u>call Voom_TreeSelect(0)<CR>"

it seems not work:

Error detected while processing function QuitNR:
line 11:
E488: Trailing characters: <C-u>call Voom_TreeSelect(0)<CR>
Press ENTER or type command to continue


thanks.
