Question

I’m editing HTML files.
I use this keymap to launch firefox to preview the page:

map <F6> :update<CR>:silent !xdg-open %:p<CR>

But after this command, the Vim window becomes completely black.
I need to scroll every line to make it appear again.

So I want to write a function to fresh the buffer. Here’s what i did:

function! Refresh()                                                                                                                                               
    " code
    set noconfirm
    bufdo e!
    set confirm
endfunction

nmap <F5> :call Refresh()<CR>

I got the idea from this post.
But it doesn’t work.

Use CtrlL to redraw the screen. You can also use :redraw.
