Due to the fact that he worked a little on this, it seems that this, or at least, could be done using Sublime Text. I saw several links to the save button in the search and replace panel, which looks like two rounded squares superimposed on each other.
However, I cannot find this at all in my version of Sublime Text 3 (on Mavericks) ...
I also checked the settings to see if this option was disabled, but the only link I could find was:
{ "keys": ["super+alt+a"], "command": "toggle_preserve_case", "context": [ { "key": "setting.is_widget", "operator": "equal", "operand": true } ] },
in the default keyword map file ...
Here is a screenshot of my search and replace panel:
