How to Bind a Chat Message in CS2

Quick messages save time during matches for players working with their CS2 configs. You can assign any text to any key.

Enable the console

Settings → Game → Enable Developer Console (~).

Use the say / say_team command

say "text" — sends to all chat
say_team "text" — sends to team chat

Create a bind

Examples:

bind "k" "say_team Rush B!"
bind "l" "say Need drop"

Remove a bind

unbind "k"

Save in autoexec

Create a file named autoexec.cfg in the cfg folder and add your binds there.
Launch the game with the parameter:
+exec autoexec.cfg

Conclusion

A couple of console commands — and you can send any message with a single key.
