Open Files in Split Windows

If you want to open a file in a split window, just type :RV, instead of :R, and the item you wish to open (model, view, controller, etc.) This opens the file in a vertical split. If you want to a horizontal split, use :RS

Open Files in New Tabs

You can open any Rails file in a new window just use :RT instead of :R.

Calling :2,4Rextract greeter will yield the following results:

# New buffer in vertical split: app/models/concerns/greeter.rb
module Greeter
  extend ActiveSupport::Concern

  def greet
    "Hello World"
  end
end

# Buffer: app/models/foobar.rb
class Foobar
  include Greeter
end

It is also extracting view(s) to partials

Tcomment

As operator (the prefix can be customized via |g:tcommentMapLeaderOp1| and |g:tcommentMapLeaderOp2|):

gc{motion}   :: Toggle comments (for small comments within one line 
                the &filetype_inline style will be used, if 
                defined)
gc<Count>c{motion} :: Toggle comment text with count argument 
                (see |tcomment#Comment()|)
gcc          :: Toggle comment for the current line

Explicit commenting/uncommenting:

g<{motion}   :: Uncomment region
g<c          :: Uncomment the current line
g<b          :: Uncomment the current region as block

g>{motion}   :: Comment region
g>c          :: Comment the current line
g>b          :: Comment the current region as block

In visual mode:
