It's well worth spending some time reading the AE help pages. One of my
favorites is "help +" which ends with the gem "We could go on and on about
this, but you probably get it." I'm a huge fan of AE, even though I spend most
of my programming time inside a visual editor (I like joe
[http://joe-editor.sourceforge.net/], not to start a religious debate). I
don't use AE prestores with the wild abandon of my misspent youth, but they're
still a handy thing to know. If anyone knows the author of AE, let me know - I
owe him or her several drinks...
The backtick is just the default 'command delimiter'. You can read more about
it with:
*--: help delimiter
Command: CDelimiter (CD)
'CD' allows you to change the command delimiter to any single character.
When you enter the editor for the first time the command delimiter is
set to the ` (weirdmark, not single quote) character.
Examples:
*--: CD [displays the current command delimiter; no change]
Command delimiter is `
*--: CD# [changes the command delimiter to '#']
Command delimiter is now #
The Command Delimiter is a single character that separates multiple
editor commands when they are entered at a single editor prompt.
Valid command delimiters are:
` , ; # $ % & ~ | [ ] { } / " '
<and then onto prestores>
Example:
*--: G10`G20`G30 [go to line 10, then to 20, then to 30]
A rather pointless command, but it illustrates the principle.
Multipart commands are very useful as prestored commands. They allow
processing many records with a single command. For example, suppose
you had a select list of 100 records, and each of them needs every
occurrence of '100' changed to '250'. You can do this with a multipart
prestored command.
First create the prestored command:
=DOITALL CU9999/100/250`FI`=DOITALL
Then run the command '=DOITALL' by entering '=DOITALL' as a command.
The editor will then loop through the list of records, perform the
change for each of them, file each of them, and then run =DOITALL again
on the next record.

Unreal. This old dog just learnt a new trick.
