Pause jump / Halting

The Pause jump involves jumping and then halting the roblox client process by holding the mouse button on the close button.
This can allow you to hover in mid-air for short durations (20~ sec max)

You can also get a unique bounce when falling from great heights as demonstrated in some parkour games.

I haven't found a useful application for this glitch in-game yet, apart from showing people you can hover.
