how do I unmap just some mappings?

[DWIAltonaAnalytics]

Description

this might be related to #1673 or #1783 but these did not help me.

I use vimtex throug vims package mechanism, and have it in pack/foo/start/vimtex/

I use a dvorak keyboard layout and have remapped some keys, I end up using t instead of j to move down.

now this conflicts with all the nmap from vimtex starting with a t, and everytime I want to move down a line, there is that pesky wait until the cursor moves.

I tried different approaches:

adding nunmap t** to $vim/after/tex.vim and my vimrc but that did not remove the mappings, I get an error that these mappings do not exist. if I do packloadall in my vimrc it is still the same.

I added mappings for t** stuff in my vimrc, called packloadall and then removed them again, but that didn't help either.

how can I remove just some of the mappings VimTeX provides without disabling them all?

Steps to reproduce

load vimtex with vims package mechanism

have no t j in your vimrc, open a latex file and try to move the cursor down by pressing t

wait for a tiny bit to see the cursor move.

Expected behavior

I can unmap any mapping created by vimtex

Actual behavior

unmapping does not work.

Do you use a latexmkrc file?

no

I use vimtex throug vims package mechanism, and have it in pack/foo/start/vimtex/

Cool. Notice that I personally strongly prefer a plugin manager. For Vim, I've found vim-plug to work very well. But the builtin package mechanism is probably also fine, if you know what you are doing.

I use a dvorak keyboard layout and have remapped some keys, I end up using t instead of j to move down.

now this conflicts with all the nmap from vimtex starting with a t, and everytime I want to move down a line, there is that pesky wait until the cursor moves.

In this case, I would advice the following: Either disable all default mappings and make your own. Use let g:vimtex_mappings_enabled = v:false to disable. See the map targets under :help vimtex-default-mappings for the mappings you want to create.

Or you can use g:vimtex_mappings_prefix to adjust the <localleader>l prefix and then remap the keys you want to override in your personal $vim/ftplugin/tex.vim.

Notice that you should not put it under after/, because VimTeX will avoid creating mappings to <plug>(...) targets that already have a map.

I tried different approaches:

adding nunmap t** to $vim/after/tex.vim

You probably wanted $vim/after/ftplugin/tex.vim; but see my previous comment.

Hi, thank you.

I went with the g:vimtex_mappings_enabled = v:false in my vimrc and added the mappings I was using to my $vim/ftplugin/tex.vim

I can add more if I need them.

[DWIAltonaAnalytics]

fixed.

[lervag]

I think that's a very good approach.
