/*QUAKED func_wall_toggle (0 .5 .8) ? FTW_STARTHIDDEN
Brush that can be hidden and reappear when triggered.

-------- KEYS --------
"targetname"    Name

An alternative is func_brush, which also can control aspects such as collision.
If FTW_STARTHIDDEN is set, it'll start hidden.

-------- TRIVIA --------
This entity was introduced in Half-Life (1998).
