CI = Change Invisible.

CV = Change Visible -- that is, the program stops at every
appearance of the string to be replaces and asks if you want to
make the change, or not make the change, or quit that process, or
stop after making the change.

In XyWrite III + (and in earlier versions, as best I can
remember, you could use ANY mark of punctuation, so long as you
used the same one for the three markers: beginning, middle, and
end. Thus ?old_text?new_text? will work just as well as the
example above.

Search (or se) will find the next occurrence of specified text:
SE \whatever\ without distinguising between upper case and lower.

Search Absolute (sea) takes case into account. sea ;What; will
look for What and ingore WHAT or what or wHaT.

Search backward (seb) will find the immediately previous
occurrence of specified text.

As explained above, there is cv, which asks for verification
before making each substitution. Also, cia takes case into
account, as does cva, when searching. The substituted string
always follows the case of the string on the command line.
