Vim中Python函数帮助滚动问题（YouCompleteMe相关）

Hey there! I totally get being a new Vim + Python IDE user—let's get this sorted out for you.

First, let's name that feature you're using: what you're seeing (the pop-up with np.random.randint's parameters and docs) is called signature help (sometimes referred to as parameter hints) in YouCompleteMe. That's the auto-completion-related feature you're asking about.

Now, for scrolling through the content in that pop-up:

• By default, YouCompleteMe uses these key bindings to navigate the signature help:
  • Press <C-n> (Ctrl + n) to scroll down to the next parameter or section of the documentation
  • Press <C-p> (Ctrl + p) to scroll back up to the previous parameter/section
• If those don't work for you, you can also use standard Vim window-scrolling commands while your cursor is focused on the signature help pop-up:
  • Ctrl + e to scroll down one line
  • Ctrl + y to scroll up one line

If you want to customize these shortcuts to something more intuitive for you, add these lines to your .vimrc file (replace the keys inside the brackets with your preferred bindings):

let g:ycm_key_list_previous_signature = ['<S-Tab>']  # Shift + Tab for previous
let g:ycm_key_list_next_signature = ['<Tab>']        # Tab for next

Just a quick check: since you're already seeing the signature help pop-up, your YouCompleteMe Python setup is working correctly—no need to reconfigure the core Python support here. Just focus on the scrolling bindings above!
