Basic Jump used horizontally(?)

[Caira Ayryn]

This isn't something I was planning to use for my character, (I am planning to start out with Ranged proficiency) but I had a question.

Can basic jump be used horizontally? I assume yes (?) but to some extent, but I wanted to know if speed plays a significant factor in this move.
(Side note I recognize the move is quite different from burst.)

Secondly, can a horizontal jump be used in association to a charge at an enemy? (Ie. Perhaps easier than running at an enemy, because there is less traction, aka "gliding" through the air) this tactical side of the move interests me. But maybe I am overthinking it.

Also I recognize that a "jump-charge" as it may be called, is somewhat of disadvantage because there isn't much time to dodge.

Thirdly, would a horizontal jump* be beneficial in a stealth prioritized situation because footsteps wouldn't be heard approaching to alert an enemy (from behind)?

*again basic jump

Edit: also as to whether something like this can be used in battle
I hope someone can clear this up for me. Thank you in advance.
