Call and Send?

[Steven Fernandez]

This is another newbie Transcript question. I'm going to try to be
careful with my "new user question" credits :-)

1. Are Call and Send the same thing with different syntax?

2. In the Dictionary is says this about the send command:

"Using the send command is slower than directly executing the commands
using the normal message path."

If I have a handler called x in the stack script, is there a better
way of passing message x to that handler without using send? Are they
just talking about system generated messages such as mouseUp?
