# Coercing Casing With vim-abolish The [`vim-abolish`](https://github.com/tpope/vim-abolish) plugin provides a couple handy shortcuts for quickly coercing the casing of a variable. For instance, if you have a variable in camel case and you want to change it snake case, you can navigate over the variable and hit `crs` (e.g. `myFavoriteVariable` -> `my_favorite_variable`). Similarly, you can hit `crc` to change a variable to camel case. It even has support for mixed case (`crm`) and uppercase (`cru`). h/t Jake Worth
