Suggested mapping in README about glow.nvim

[anihm136]

One way to solve this would be to set a custom filetype for the preview buffer in the plugin (say, glowpreview). Then, while setting the mapping, the autocommand can include that filetype as well. Thoughts?

I cannot toggle the glow preview window by hitting because the mapping is not enabled in the preview buffer.

So are you suggesting to have the same mapping added to call the window and to close it? like a toggling feature? The current :Glow command already works as a toggle, so if you call the original mapping it will already close the window

I want to map some key (in the above example, <Space>) to :Glow<CR> only when file type is markdown, not global. The problem for doing this is that the mapping is not available in the preview buffer. So I proposed enabling to customize mapping to toggle preview window in the preview buffer.

This is what i am not understanding. Do you want a custom mapping to trigger the window AND another one for closing it?

Yes. More precisely, I need

augroup glow
autocmd!
autocmd FileType markdown nnoremap <buffer> <silent> <Space> <Cmd>Glow<CR>
augroup END

to open a preview window by typing <Space> only in markdown file type, AND

-- In lua/glow.lua around lines 115-118
api.nvim_buf_set_keymap(buf, "n", "<Space>", ":lua require('glow').close_window()<cr>",
                                            {noremap = true, silent = true})

to close the preview window, because the above autocmd does not work in the preview window.
