I am starting to use Neovim and in the process of configuring the text editor. While doing some test I found that every time I try to open a file using the :Ex command I get the error:

Error detected while processing function <SNR>28_NetrwBrowseChgDir
line  172:
E471: Argument required: keepj keepalt 2wincmd 1

Only if I previously had used the :Lexplore command.

I have no idea why this happens neither how to solve it, so I appreciate all the feedback you can give me.

    This sounds like a bug in netrw. Please file a report with Dr Chip or on theVim repository

    No: Netrw is the plugin that ships with Vim and provides the :Explore family of commands. (I didn't realize Neovim even still shipped Netrw, actually. They mostly copy over stuff like that from Vim, though.) Dr. Chip is the maintainer. Try :edit $VIMRUNTIME/plugin/netrwPlugin.vim or :help pi_netrw for contact info.

I stumbled upon that issue too. It seems to me that with 99% its Lex bug. I switched to Vex + some tunning and that works fine. With Lex I couldn't make Ex open files after Lex =\

Update 2. Sorry. New observations) I made full analogue of Lex with Vex and .... is start behave like Lex. More inspections lead me to -- vim.g.netrw_browse_split = 4. Exactly this thing make all this work wrong. If you can normally handle it (like I'm trying right now) I suppose you can I achieve this sfuff working.

Update 3. Yes it works. If when I open Lex/Vex I set vim.g.netrw_browse_split = 4, but when I open Ex revert it to default vim.g.netrw_browse_split = 0 all works like a charm.
