[Fernan Bolando]

1. insert a character in a line? - I usually retype the whole line with .c
2. indent a line - i usually retype the whole line.

If you want to change:

"in ed, how" to "in fred, how", do something like this:

s/in ed/in fred/

if you have a line in the form:

> foo bar BAZ frob knob

and want to insert text after BAZ, do:

s,BAZ,&  new text new text,

where the `&' stands for whatever was matched; here BAZ.

to indent several lines, you could do
1) set dot to range, like 1,5
2) s,^, ,g

(a tab between second and third coma)

but that'd indent the empty ones too :(

you want

1) set dot to range, like 1,5
2) s,^.,        &,g

(a tab between second coma and the ampersand)
the `g' means `do it for every line, rather than just the first one'

back when I was text-moder on an 486, mouse via gpm was quite a speed-up for 
work in Midnight Commander and CLI [1]
but porting gpm to p9 would require cursor addressing, you don't what that.



[1] yea, yea, bash completio. linux normally have several virtual terminals... 
but bash is oblivious to whatever happens on other ones. and grepping 
/dev/<virtual-terminal> is, well... :P

I believe you can't set dot to a range in ed, just to a single line. Your
sugestion applies to sam, though. In ed, you should give range with
command:

1,5s,^,	,g

As a guy who first read the book around 40 years ago, I can endorse the recommendation.
