Re: [StrongED] Re: S & R query

I think it would be useful to have a "getting started" page for 
Advanced S&R. (In index2.html there is a line for Advanced search and 
replace, but it isn't a link.)

For example I have just noticed that in the examples, things like @1 
and {X} are separated by spaces. When I was trying to construct such 
things I didn't put spaces in, as i didn't want it looking for spaces 
there. Of course, it would not be, as the spaces would have to be in 
quotes for that to be the case, but it wasn't intuitive.

Are the spaces between "keywords" necessary, or just to improve 
readability?

Is there a way to create long expressions outside the relatively small 
window?

Is there a wasy to store commonly used ones for future use?

The situations where end-of-line is not significant are relatively few 
- html and plain text are the only ones I can think of. Even in plain 
text, collapsing whitespace to a single space using "white" would join 
lines (not a problem) but would also merge paragraphs, which is likely 
to be unintended.

The confusing part is the definition - '\t\x0A' expanding to be space, 
tab, newline, carriage return and others. \x0A ia specifically one 
character, so the rest must be the expansion of \t. In which case, 
what is the key for tab?
