you can create an alias, which you can either type in the channel editbox or add it as a right-click item in the popups menu. Pressing Alt+R takes you to the scripts editor, where you can place aliases.
alias asl {
/msg $$chan age: none of your business sex: not your business either location: even more not your business
}
In this case, using "/say" is the equivalent of the "/msg $$chan". The double dollar halts this if used where $chan is not defined, which keeps it from trying to send a query message to the next word.
To send it like you would do "/me message", change the "/msg" to be "/describe"
You can also add this as an item in the right-click menu of your channel, where you currently see "channel modes". You can do this 2 ways.
1. Press Alt+P to reach the popups editor. Within that editor, use its 'view' menu to choose 'channel' where it currently has:
Channel Modes:/channel
You can add your own "label:command", for example adding the row:
Show ASL to channel:/asl
... which will run the above alias example.
2. In the same script file where you created the above 'alias asl', you can also add several rows:
menu channel {
Show ASL to channel:/asl
}
... and it does the same thing. You can find more info on these from:
/help Popup Menus
/help Aliases
