For those times when u need to be doing something other than clicking mouse 1 to fix your sentry, simple engy script that just toggles crouch and fires, so just sit by your gun and dispenser, press mouse4 or desired key and you will crouch and repair.
//Duck Toggle
alias duckToggle "duck1"
alias duck1 "+duck; +attack; alias duckToggle duck2"
alias duck2 "-duck; -attack; alias duckToggle duck1"
//Duck Toggle Key Binding:
bind "mouse4" "duckToggle"
Enjoy all that free time, while still doing your bit for your team

, and of course play better after resulting calmness
