I appreciate your concern and your many good efforts on behalf of the
product we all love.

It gives them to you sequentially, and it opens the script window on
the first hit. After that, you use the "find next" button in the
search-and-replace script window to get subsequent hits. It finds the
desired strings pretty quick, though Rev finds them faster.

Well... I might not have been clear. Searching scripts in Rev is
fine. Better than fine. Searching field text with Rev's "find" stack
is the problem in Rev.
The absence of Atkinson's patented "hint bits" might be part of the
problem with finding field text in Rev, but it's probably not the
A simple script that finds field text using the "find" command works
fast enough in Rev. It's just Rev's native "find" stack that is way
e.g. the following script takes less than 1 second. Okay, it's a
clunky script, but it works. Homie don't script elegant-like.
put 1 into countVar1
put 1 into countVar2
repeat until CountVar2 < countVar1 or the shiftkey is down
put the number of this card into countVar1
find string "software"
put the foundchunk & return after theVar
put the number of this card into countVar2
put theVar after cd field "temp"
This script takes a second or two, in Rev in the stack I used to test it.
The same task in Rev's "find" stack takes 15 to 20 seconds, searching
the same stack.
It is offputting, I must say, that the Find stack is so very slow, at
least when it comes to field text. It gets much, much worse with
larger stacks, containing many fields per card, and many cards. In
those stacks, Rev's simple find command still works great.
