As said on the issue tracker: Any situation I’ve ever seen where someone uses invert they could have used a simpler combination of key bindings.
- Search for (?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)
- Invert Selection
- Press Enter
That leaves you with every IPv4 address in the file, one per line. How much simpler can it be? Clicking Invert Selection is practically muscle memory at this point.
If you use it often I’d suggest making a keybinding for it.
If I wanted to memorize dozens of cryptic, text editor key bindings, I would have just stuck with Vi (an editor first released about the time I started writing software).
I don’t need another key binding to memorize when there are literally thousands of key bindings between the various operating systems, tools, and applications that I use. There’s already about five dozen in Sublime. There are more than 60 of them in the browser I’m using to write this. My email client has more than 70 key bindings. The list goes on an on with IDEs, office suites, photo editors, video editors, sound editors, etc. And God help you if you have the wrong window in focus when you try to use a key binding, because the results could be disastrous if there is a collision in key bindings between the apps.
I have a better suggestion: Restore the Invert Selection menu item instead of arguing with everyone who came to rely on it.
