Binds question

I have made my own binds, I was wondering if it was possible to bind more than 1 command to a key. Example would be "ai_reaction_delay_idle 99999" and "ai_reaction_delay_alert 99999" on the same key. And also how or is it possible to do toggle on and off binds. press key once to toggle on and press again to toggle off. Thanks in advance for any help in this.

Its possible:
bind "key" "command1;command2;var 123"

Edit:
Toggle is a bit more complicated. You can do it like this:

alias toggleon "command1;bind f9 toggleoff"
alias toggleoff "command2;bind f9 toggleon"

The problem is, that these aliases need to be in the autoexec.cfg (or valve.rc), i guess both are encrypted ._.

That sound like alot of work i would rather bind 2 different ones like 1 with delay 999999 and the other with delay 0 or 1 or whatever the default is.
