To use Q2 lmctf sounds....
make a copy of each male_<sound>.wav
and call it fem_<sound>.wav
put all the .wav's in the lmctf/sound/radio directory (make the folders if needed)
when playing LMCTF, in the console, type
play_team <sound>
ex:  play_team dadada

or bind it to a button:
There are new commands for key binding on the keypad located at the
(number lock, /, *, +. - ) pad area . You know, over on the right
side of the key board. These keys can be bound separately from their
corresponding duplicates elsewhere on the keyboard. . So this gives
us 15 more available keys for binding commands. Here is an example:

bind "KP_DOWNARROW" "say How'd You Like That Kung Foo Shit?"

bind "pause" "play_team <sound>"
bind "KP_SLASH" "play_team doh; say doh!"
bind "KP_MINUS" "play_team lockstep1; exec lockstep1.txt"  //{put lockstep1.txt into your lmctf folder}
bind "KP_HOME" "play_team bowdown
bind "KP_UPARROW" "play_team 
bind "KP_PGUP" "play_team 
bind "KP_LEFTARROW" "play_team 
bind "KP_5" "play_team 
bind "KP_RIGHTARROW" "play_team 
bind "KP_PLUS" "play_team 
bind "KP_END" "play_team 
bind "KP_DOWNARROW" "play_team 
bind "KP_PGDN" "play_team 
bind "KP_INS" "play_team 
bind "KP_DEL" "play_team 
bind "KP_ENTER" "play_team 

Whatever you bind to the "PAUSE" key will also be bound to the "NumLock" key. But not vise-versa.
