# `GSFont.kerningLTR`

*Instance Property*

Left-to-right kerning data.

## Declaration

```swift
var kerningLTR: MGOrderedDictionary<NSString, MGOrderedDictionary<AnyObject, AnyObject>> { get set }
```

```objc
@property (nonatomic, strong) MGOrderedDictionary<NSString *,MGOrderedDictionary *> * kerningLTR;
```

```python
pyobjc_instanceMethods.kerningLTR() -> MGOrderedDictionary<NSString *,MGOrderedDictionary *>
pyobjc_instanceMethods.setKerningLTR_(kerningLTR: MGOrderedDictionary<NSString *,MGOrderedDictionary *>)
```

## Discussion

The outer dictionary is keyed by master identifier. Each master dictionary maps left-side glyph identifiers or group keys to dictionaries of right-side glyph identifiers or group keys. The innermost values are kerning values.
