2 Mapping Questions

I have been mapping for quite a while, and I am in the process of making a map. 2 questions though:

1.) How do you make a space where a player can "float" up to another surface? like if there was a ladder or water there but without either of those.

2.) MOST IMPORTANT: How would i make something that would give a player a boost in speed while on a surf map?

thats it. Thanks in advance.

1) You can use trigger_push regions, but those will only work upwards if you jump.  You can't actually make someone move upwards without them initiating the action first, unfortunately.

2) Once again, you can use a trigger_push, or another way is to use func_conveyors... but those won't work (I wouldn't think) for surf maps.
