The command "Toggle Radar Wormholes" is listed under Options -> Controls -> Keyboard. If you assign it to a key from that dialog then a message will be printed to the console saying that there is no such command as ToggleWormholes.

The related toggle radar commands are simply aliases, so the fix should be as simple as including an alias for ToggleWormholes in the default wgaf file that gets generated on fresh installs.

I did a bit of experimenting, and the correct alias appears to be:
alias togglewormholes "radartoggle 21"

Don't forget to update the showall alias to include wormholes too:
alias showall "radarshow 3 4 5 6 7 8 9 10 11 12 21"

Similarly, when attempting to assign a command to "Chat to Help Channel", a console message is generated saying there is no such command as Say_Help.

Say_Help should be this:
alias say_help "join 1; say_channel"
