does it do the same thing as the Multi Blocker?

 It looks roughly equivalent, yeah.

If you hold down a button, a Keyboard Watcher set to "down" will trigger over and over. Example Gif

If you put a Multi Blocker between them, it's better, but the Multi Blocker only prevents re-triggering for a period of time, meaning it's possible to re-trigger. Example Gif

If I have something I want to trigger once, and only once, per Scene, I send the trigger through a Gate that initializes on and feeds into a Trigger Value actor that turns the Gate off after it lets data pass the first time. This makes it a one-time-only trigger (until I leave and re-enter the Scene). Example Gif

If I have something I want to trigger multiple times in a Scene, but that I'm afraid might accidentally get triggered more than once at a time, I use a Keyboard Watcher set to "up" instead of "down" so that holding down the button cannot accidentally trigger it more than once. Example Gif
