I know alot of people have been asking around for railjump binds, so here is one.
I like to use this bind to quickly escape from trouble, however those noobies out there that want to use this should know, good rail jumping is a skill, and one that will not be immitated by a rail jump script. You should use a rail jump script sparingly as it will not help you get better.
set rjump"+lookdown;wait;wait;+attack;+moveup;wait;wai t;-attack;-moveup;-lookdown;-lookdown;wait;wait;centerview"
[previous should all be on one line]
then to bind it to a key you would have...
bind f8 vstr rjump
provided f8 was your chosen key.
peace, and enjoy=noobs
