From the Ubuntu bug report:
"
I use find/replace tool. And want to replace "fourth" to "fifth", for example.
If there is a word "Fourth" with a big first letter, it replaces to "fifth". And
I want to get "Fifth", case sensitive. I hope, I translated normally.
--
Use the 'match case' option in find/replace (my response to user)
--
No, it doesn't help. It will be find just exactly word with this option. And
again, if I enter the word "fourth" to the "Find" field with 'match case'
option, the word "Fourth", "foUrth" etc. will not be find. And I want to find
all possibilities of word with differrent letter case in it and replace them to
the similar word from "replace to" field. For example, "fourth" -> "fifth",
"Fourth" -> "Fifth", using ONE replacing operation, how it can be made in MS
Word. You may try and look, how it works there. Thanks.
