I know that with Vim\'s substitution command you can specific a range of lines:
:12,24s/search/replace
I want to be able to specify a range
Using Narrow Region plugin we can open a temporary buffer with the range we need to search or change
:900,1000NarrowRegion
Then we can meke a search
/thing
Or a change and write the buffer back
:%s/this/that/g :wq
