Not all of them, for example these don't work properly:
vote yes/no, ready/unready, dropweapon, say_team something...
also when I want to chat in the console and I type something, I have to do a series of 3-5 uparrow/enter before it pops green on screen
or when I want to vote from the menu map/kick/shuffle I have to do it more than once, sometimes it works the first time, but usually I must do it 3-5 times.
It happens only online, during practice with bots everything is fine.
