:VimtexTocToggle not working inside the TOC buffer

[ChausseBenjamin]

Description

When inside the VimtexTOC buffer, typing the :VimtexTocToggle commands returns the following error:

E492: Not an editor command: VimtexTocToggle

This is due to the fact that the VimtexTocToggle command is exclusive to tex filetypes (and it's derivatives such as rnw).
Since the toc buffer has no filetype( running :set filetype returned filetype=), I deduced this was the issue.

This is especially annoying when mapping a key to open and focus the TOC as it no longer works as a toggle
(ex: nnoremap <c-Tab> :VimtexTocToggle<CR><c-w>l).

Steps to reproduce

1. Open a latex document
2. Enter :VimtexTocToggle
3. Enter <C-w>l (or j if your split is horizontal)
4. Retype :VimtexTocToggle
5. Enjoy!

Expected behavior

The Toc window disapears and the cursor returns to the previous tex buffer.

Actual behavior

ERROR:

E492: Not an editor command: VimtexTocToggle

Do you use a latexmkrc file?

No

I've added the command for the ToC window now - does that resolve your issue?

Yes Thank you!

Glad to hear it :)
