@ -60,7 +60,7 @@ You can chain as many modifier functions as you like!
## Modifier functions
There is a bevy of supporting functions to customize your keycaps. You can add a brim to more easily print the stem with `brimmed_stem_support`, make 2x2 keycaps with `2u() 2uh()`, add legends, rotate stems, and more. All these functions manipulate the settings available to you in [`settings.scad`](https://github.com/rsheldiii/KeyV2/blob/master/src/settings.scad), though [some of them](https://github.com/rsheldiii/KeyV2/blob/master/src/key_transformations.scad#L128) are quite complex.

These modifier functions can be found in [`key_profiles/`](https://github.com/rsheldiii/KeyV2/blob/master/src/key_profiles) for different keycap profiles, [`key_types.scad`](https://github.com/rsheldiii/KeyV2/blob/master/src/key_types.scad) for predefined settings for common keys (spacebar, left shift, etc), [`key_sizes.scad`](https://github.com/rsheldiii/KeyV2/blob/master/src/key_sizes.scad) for common unit sizes, and [`key_transformations.scad`](https://github.com/rsheldiii/KeyV2/blob/master/src/key_transformations.scad) for everything else. I encourage you to do some sleuthing but for a list of (most) helper functions with explanations, [Check out the wiki!](https://github.com/rsheldiii/KeyV2/wiki/KeyV2-Helper-Documentation)
