Just to explain Groups/Saved Searches with pictures:
1. Press
Ctrl+F to open Find/Replace.
Change the
Mode + All HTML Files to what you want use. In this case, I have "Regex" + "All HTML Files".
2. Press
Tools > Saved Searches.
In the Saved Searches window, you're able to create Groups of searches (groups appear
Bold).
Create your entire set of Find/Replaces.
3. When you're ready to run the entire batch of Find/Replaces at once:
Highlight the group you want to run (#2 in the image).
Then press
Replace All (#3 in the image).
