Using Sublime Text 2 - Is it possible to insert a line break/text return after a specific String in a text file e.g. by using the Find ‣ Replace
Using the Find - Replace tool, this can be accomplished in two different ways:
Click in the Replace field and press Ctrl + Enter to insert a newline (the field should resize but it doesn't, so it is hard to see the newline inserted).
Inside the Find - Replace tool, activate the S&R regex mode (first icon on the left .*, keyboard shortcut is Alt + Ctrl/Cmd + R to activate/deactivate it).
Type \n in the Replace field wherever you want to insert a newline.
Both solutions also work if you want to find newlines, just do it in the Find field.
