Shared online as the Half-Life menu click, this brief UI sound is associated with Valve's classic first-person shooter and its spare, functional menus. Short interface sounds travel well because they are easy to drop into edits without explaining them, and this menu click has been reused across gaming clips, streams and memes as a shorthand for making a choice. Like another short click sound, it works best when it stays brief and recognisable, which is why creators keep returning to it for retro PC gaming edits.
