Thank you for your work! It's a really helpful guide and I learned a lot from it

https://github.com/iggredible/Learn-Vim/blob/master/ch13_the_global_command.md#advanced-sort

However, in the section above, it says that This command also follows the form :g/pattern1/,/pattern2/command, but I can't find anything about this form from the doc

In my opinion, it should be illustrated like this:

• :g is the global command pattern.
• /\[/ is the only pattern. It matches a literal left square bracket "[".
• +1,/\]/-1 is a range, it begins from the line below the current cursor position (current cursor is placed at [), to the line above ]. thus, if not abbreviated, it should be written as .+1,/\]/-1.
• sort is the command-line command which the range applies.

If I add a dot before +1, it works well, that's why I think this explanation makes more sense.
