`+` not recognized
When I press `SPC n +` it says
```
key bindings is not defined: [SPC]-n-<80>
```
This is a fresh installation and the older `init.vim` file is replaced by the one by `SpaceVim`
I have just added the following lines
```vim
set guifont=FiraCode\ Nerd\ Font:h12
set number
set relativenumber
```
The following was already present
```vim
execute 'source' fnamemodify(expand('<sfile>'), ':h').'/main.vim'
```

The following is my `init.toml` file
```toml

```

But I can't use `+` either for going to `count` lines after the current line or for the above purpose.
