Change name key binding

[MacNetron]

I try to add a key binding to change my name. I know I can change my steam name, but I just want to change my in-game name, not the steam name.

Normally you type in the console:
setinfo name "MacNetron <TWM|TF2Maps>"

But I want a key binding to make things faster.
There the problems unfortunately start...

alias "change_name" setinfo name "MacNetron <TWM|TF2Maps>"
bind "F12" "change_name"

Doesn't work. Probably a "" issue.

Trying to get rid of "" gives
alias "new_name" "MacNetron <TWM|TF2Maps>"
alias "change_name" "setinfo name new_name"
bind "F12" "change_name"

Which renames me to 'new_name'.

Suggestions?

Also, all that trying around, I appear to have deleted the cancel build for the enigineer, as it shows now: "hit '< not bound >' to cancel".
How do I rebind that option, because sometimes I need to cancel to shoot back :)
