Error running `<C-e>`

[diego898]

I am new to vim and tried the following line:

" You don't know what you're missing if you don't use this.
nmap <C-e> :e#<CR>

and got the following error:

E194: No alternate file name to substitute for '#'

Ah, sorry that's not clearer. You need to have opened at least two buffers in Vim. You can read more about this approach in my first Vim article: https://statico.github.io/vim.html#vim-the-terminal-buffers-and-you

When I launch it with:

vim foo.txt bar.txt quux.txt quuxi.txt

and then try it, it still throws the same error

Right, you have to edit another file from within Vim first. Try running that command and doing :next from within Vim, then try Ctrl-e again.
