I use Sublime. I know, I know, I’m not a “real” dev. Whatever. It works for me. One of my favourite features is the multi-cursor. If you're a fellow Sublime user and aren’t aware of this ability you should really check it out. Look at step 12 for a little gif of what it looks like.
This is an awesome tool for making bulk edits in a file.
cmd + mouse-click is where I started, but then @gerwinvanroyen told me about selecting a bunch of lines and then doing
cmd + shift + L to select all the lines individually. Also running a
find all in Sublime and then using the multiple cursors from there has been really helpful.
So go try it out - it’s pretty powerful!
