The example is an alias - for a remote file (every alias definition in a remote file is indicated by the initial word "alias"). Simply remove this word if you want to put it into "aliases".
It doesn't matter whether the alias is in the remote file or in "aliases" if you set a trigger to call the alias. The trigger itself has to be inside a remote file of course - so why not keep the two parts together in the same file
You could as well place the command right inside the event of your trigger...
Also note that you'll see the first message at the moment the timer fires for his first time, not at the moment the alias is called and the timer starts.
