Air walk

How to perform
There are a few ways to get airwalk :

With Float/Persistent Float, float a few pixels above a platform.

Or with Float/PFloat, leave an elevator while it is moving.

Or with Float/PFloat, walk over a lever (at a specific height).

Alternatively, dash/walk over a seam in the ground and buffer a jump right after.

Effects
Airwalk tricks the game into thinking you are walking on solid ground, when in reality you are in midair. This causes you to be able to dash and still retain an air dash. You can also jump with airwalk. However, in the non-float setup, you need to hold jump to keep airwalk.

How to get rid off
Start falling, get hit, open inventory, or go through a transition.
