New installs get ST3 installed by default, even if I don't have a plan to use it on that machine, I treat it as if it was a Notepad on windows back in the day.
Wonderful piece of software.
1. Select something at one line
2. Select other occurances of this something using CTRL + d
3. Move the cursors with the arrow keys, by using ALT + Arrow to jump to word boundaries HOME to jump to the beginning of the line for Ll lines that had a cursor on them, END to jump to the end, draw selections by holding SHIFT while doing any of that.
The thing is, when you got this it can be much faster than crafting up a regex in Search/Replace even if you are good with regexes.
For find and replace, I have to leave the editor and go to a different tool window. Also, my regex skills are sometimes lacking when I want to find something on a deadline. I only use find and replace when I have to do the same refactor across files.
