The mechanism
How do you clip a Twitch stream without recording it?
This is the mechanism, and it is the reason the FPS claim holds up.
While you are live, Twitch is already holding the recent past of your stream on its own servers. That buffer is what the Clip button on your channel page cuts from. It exists whether or not you ever use it.
When you press the hotkey, Boltis sends a single request to POST /helix/clips, Twitch's official clip endpoint, asking for the last 60 seconds. Twitch cuts the clip on its own infrastructure and hands back a link. Your PC sends a web request and receives a reply. That is the entire local cost.
Tools that record locally have to capture and encode video the whole time you play, on the chance that you might want the last minute. That is where the FPS cost in other approaches comes from, and it is a cost Boltis does not pay because it never records anything.

Performance
Does clipping affect your FPS?
No, and the reason is structural rather than a matter of optimisation. There is no capture loop, no encoder and no disk writing during gameplay, so there is nothing to be expensive.
The trade Boltis makes in exchange is that it can only clip what Twitch is already holding. You cannot clip something that happened offline, and you cannot clip a game you are not streaming. Local recorders can do both. If you are live on Twitch, you do not need them to.
The key
What is the Twitch clip hotkey in Boltis?
Ctrl+Alt+H by default. It works while a game is fullscreen, because the key is registered globally with Windows rather than inside the Boltis window.
You can change it to anything. Boltis listens for your next key press rather than offering a dropdown of allowed combinations, so whatever your hardware can send is available.
That includes mouse side buttons. If your left hand is on WASD during the moments worth clipping, binding a thumb button is usually better than any keyboard combination.
The point
How do you clip highlights without scrubbing the VOD?
By deciding at the time instead of afterwards. You already know when something was good, in the moment, with no review needed. The hotkey turns that knowledge into a saved clip before it fades.
The alternative is scrubbing a five hour VOD after the stream, or handing it to a tool that guesses which parts mattered. Both mean re-watching your own stream to find something you already noticed live. The longer argument is here.
Where it lands
What happens to the clip after you press the key?
It lands in two places at once. It is a real Twitch clip on your channel, exactly as if you had made it from the Twitch website, and it appears in your Boltis library ready to edit.
Most clips die in the Twitch clip list because getting one to TikTok means downloading it, finding an editor, cropping it to vertical and captioning it. Boltis skips that gap: the clip is already in the editor that does the vertical layout and the captions.
The other two ways
What if your hands are busy?
Two options, both covered on their own pages.
The !clip chat command lets your mods or viewers mark the moment instead. They already know when something is good, and the clip still lands in your editor.
ClipFor points the hotkey at another live channel, which is also how you test the whole loop before you have ever gone live yourself.
