How to use Teleport in tr_walkway [TF2]

Found in readme of tr_walkway (perhaps you missed it?) :

"The players can teleport around the map using the console command "tr_teleport". Hit or shoot the

yellow and black blocks around the map to change the teleport destination. Bind tr_teleport to a

key of your keyboard to help you to move faster and lose less time walking. To do it, write

in the console:

bind [key] "tr_teleport"

Replace [key] to any key you want and then press enter to load it. Press the selected key

to activate the teleport.

There are more commands for the map that can be useful to bind, like "tr_attackonce"

and "tr_stop". More information about these in the console commands section."

remember, console is the ~/` key (above tab)
