// Works by calling element.focus() and element.blur().
// Most of this was written by Gemini, which is objectively funny.
// This is my first time publishing code and actually feeling like it's not *completely* unnecessary,
// because I was actually pretty annoyed with having to use my mouse for Gemini. With this: QoL imrpovement
// achieved.
