[FTL Travel] Is there a minimum distance for any types of warps/hyperspace jumps? What's the shortest jump you could make with a given technology?

When the Enterprise goes on shakedown cruises around the solar system, is that just them warping to Saturn and back in like five minutes? Can you warp between Earth and the Moon? Or even between orbital facilities?

Star Wars hyperdrives cross much much larger distances, typically dozens of lightyears at a minimum, maybe even hundreds on average per jump. Are they able to be switched on and off fast enough to enable in-system jumps? Or if you had to run a blockade for example, could you just jump a few hundred kilometers to get past it?

Could you use two Stargates to commute to work? Or to colonize Mars? Assuming you found a way to dial them without referencing stars.

Starfleet ships have been known to use short warp jumps as a combat maneuver, actually.  This move is known as the Picard Maneuver, named after the captain that invented it.  (Not to be confused with the other Picard Maneuver, in which the user straightens his tunic after standing up, named after the starship captain that popularized it)  

The Picard Maneuver is based on the idea that information such as light can only travel to the enemy's sensors at light speed, at most.  Thus, if the Starfleet ship suddenly performs a short warp jump towards the enemy, it'll momentarily seem to be in two places at once, because the light from their original position is still making its way to the enemy ship's sensors.  The enemy's weapons would likely still be targeting the "first" ship, and would fire at it, except the Starfleet ship isn't there any more.  If the Starfleet vessel fires immediately after dropping out of its warp jump, then it's almost guaranteed to hit the enemy, while not being hit itself.
