That will run `setlocal cursorline` in the NERDTree window


## Excluding Buffers

You can exclude buffers from being highlighted in NERDTree.

Exclude "FooBar" buffers and any buffer ending in ".log" - separate multiple patterns with `\|`
```
let g:nerdtree_sync_excluded_patterns = 'FooBar\|.log$'
```
Or to exclude only "FooBar":
```
let g:nerdtree_sync_excluded_patterns = 'FooBar'
```
Or to exclude multiple specific file paths:

```
let g:nerdtree_sync_excluded_patterns = '/path/to/exclude/file1.txt\|/another/file.log'
```
