So, this is the first one I used, and I think one of the most handy too. With this you can toggle your engine on and off with one simple button, instead of two. This saves space on your keyboard and is just a lot nicer to use :

Paste each line into the console Separately

bind F5 "Engine1"
alias Engine1 "say /engine on;bind F5 Engine2"
alias Engine2 "say /engine off;bind F5 Engine1"

If you want to change the button to press (Default is F5) change all of the Bold parts to the button you want!
Enjoy!

This bind will be more adapted to the people who enjoy listening to Evoradio. It will allow you to press a single button to turn the radio on and off, again meaning that you don't need to worry about having two separate bind buttons. 

Paste each line into the console Separately

bind F6 "Evoradio1"
alias Evoradio1 "say /evoradio on;bind F6 Evoradio2"
alias Evoradio2 "say /evoradio off;bind F6 Evoradio1"

If you want to change the button to press (Default is F6) change all of the Bold parts to the button you want!

This may be handy to some people, for example an underground job. You may not want your Lifealert to go off when you are in your base because the authorities will be notified, so now you can put on and take off the Lifealert with one easy button!

Paste each line into the console Separately

bind F7 "Lifealert1"
alias Lifealert1 "say /inventory lifealert use 1;bind F7 lifealert2"
alias Lifealert2 "say /inventory lifealert remove 1;bind F7 lifealert1"

If you want to change the button to press (Default is F7) change all of the Bold parts to the button you want!

Suggested by Safira. This would be good for easly toggling Lockdowns without an issue.  

Paste each line into the console Separately

bind F8 "Lockdown1"
alias Lockdown1 "say /lockdown;bind F8 Lockdown2"
alias Lockdown2 "say /unlockdown;bind F8 Lockdown1"

Suggested by Safira. This can be used to toggle a crouch so its not FearRP/FailRP when you stand to talk 

Paste each line into the console Separately

bind CTRL "Crouch1"
alias Crouch1 "+duck;bind CTRL Crouch2"
alias Crouch2 "-duck;bind CTRL Crouch1"

A bind toggle to allow you to press a button and see your fps, ping and much more valuable internet connection information! Incredibly usefull!

A suggestion on the forums that I thought would be good as an Alias bind for those who like to swap their HUD occasionally 

Paste each line into the console Separately

bind F10 "Hudpos1"
alias Hudpos1 "say /hudpos 1445;bind F10 Hudpos2"
alias Hudpos2 "say /hudpos default;bind F10 Hudpos1"

If you want to change the button to press (Default is F10) change all of the Bold parts to the button you want! Also the Hud position can be changed to your liking by changing the value at the end of the command! 

Handy way to hide from the police. Press F11 and easily put on and take off a mask! 

Paste each line into the console Separately
F11 "Mask1"
alias Mask1 "say /inventory mask use 1;bind F11 Mask2"
alias Mask2 "say /inventory mask remove 1;bind F11 Mask1"

If you want to change the button to press (Default is F11) change all of the Bold parts to the button you want! Feel free to change the mask name to the one you have! 

Need to surrender quickly for RP situations? Sadly, you have to type it everytime or bind it onto two keys. No longer! 

Paste each line into the console Separately
Mouse3 "Handsup1"
alias Handsup1 "say /handsup;bind Mouse3 Handsup2"
alias Handsup2 "say /handsdown;bind Mouse3 Handsup1"

Physgun Wheelspeed modifier. Can switch between two different wheelspeeds.

Abuse will most likely result in a ban!
