bind x "say_team OMG WE'RE GETTING RAPED AT BASE"
It's only like 10 characters to write down the bind, it probably took you way longer to find the link to that thread.. o_O
Anyway, if you don't know, you can set bind like that temporarily for one session by entering them in the console. For a permanent approach, put the binds, one per line, in a text file called autoexec.cfg, and put it in your Trem base directory.
For some very useful binds, though, do check out the thread PIE linked; you can piece together everyone's cfg files into your own custom one. A team-join hotkey is a must for getting on the team you want, first.
