+**Maintainer:** [@dufferzafar](https://github.com/dufferzafar)
+
+Makes your enter key magical, by binding commonly used commands to it.
+
+You can set the commands to be run in your .zshrc, before the line containing plugins!
+
+```bash
+MAGIC_ENTER_GIT_COMMAND='git status -u .'
+MAGIC_ENTER_OTHER_COMMAND='ls -lh .'
+
+plugins=(magic-enter)
+```
