Game Kitchen has support for snippets. Unfortunately, there is currently no way to define your own snippets. However, there are several built-in snippets for annotations. They are:

cn - For const annotations

vr - For var annotations

pr - For param annotations

rt - For ret annotations

lt - For latent annotations

Typing any of these character pairs and then pressing tab will replace the character pair with a template for its corresponding annotation. Pressing tab subsequent times will traverse the various fields of the current template.
