Not working if set timeoutlen

[tynguyen2k1]

Explain the issue

vim-matchup(a.1 a.2 a.3 b.1) won't work if I set timeoutlen

1. What vim version are you using? If using neovim, Are you using tree-sitter or classic matching? NVIM v0.5.1 and tree-sitter

Minimal vimrc file

Please provide a minimal vimrc file that reproduces the issue. The following should often suffice:

What exactly is not working?

Do I understand that if you do not set timeoutlen then it works fine?

[tynguyen2k1]

When i set timeoutlen except for highlighting, all doesn't seem to work

[andymass]

I tried out the full config in a clean environment and everything seems to work both with and without timeoutlen, however it is very difficult to use text objects like a% and i%, they must be typed very fast.

I recommend not setting timeoutlen this low since it is difficult to press the consecutive keys this quickly.

Does this resolve the issue? Why do you need to set timeoutlen this small?
