NEED HELP WITH CS BINDS & SCRIPTS

[Alex]

Hey y'all!

I need help making a bind or script or something so that i jump and duck at the same time... i dont want to have to install a script pack or anything, just something simple plz!!

Any help greatly appreciated!

Also, for those of you with weapon buying binds, do the menus remain open after you use them? Mine do and i cant seem to get them to close automatically...
