Describe your question, feature request, or bug.

cannot scroll the preview window in vim by pressing <C-Up> or <C-Down>, but it works on nvim

Steps to reproduce

1. trigger file list

:LeaderfFile

2. select a file,  and press <C-p> to preview
3. pressing <C-Up> or <C-Down>

Actual behaviour

the whole popup (filelist and preview) vanishes

Expected behaviour

I should be able to scroll the preview popup by pressing <C-Up> or <C-Down>

Can not reproduce.

I use tmux. I fixed this issue by referring this link.

Several terminal emulators (alacritty, gnome, konsole, etc.) send special
codes for keys with modifiers, but these do not have an entry in the
termcap/terminfo database.  You can make them work by adding a few lines in
your vimrc.  For example, to make the Control modifier work with arrow keys
for the gnome terminal: >
	if &term =~ 'gnome'
	   execute "set <xUp>=\<Esc>[@;*A"
	   execute "set <xDown>=\<Esc>[@;*B"
	   execute "set <xRight>=\<Esc>[@;*C"
	   execute "set <xLeft>=\<Esc>[@;*D"
	endif

thanks!

Great.
