Vim fast way to modify method arguments

Question

One of the most common operation with source code is to modify the method arguments. Given a method argument list like this:

("argument1","argument2","argument3")

I wanna know how to deal with following operations(I use | here as a cursor position):

1. When cursor inside a quotes, and you wanna delete the contents inside the quotes. like:
   "ar|gument1" to "|"
2. same as the first one, but delete the quotes.
3. delete all the things in bracket. ("argument1","argument2","argument3") to (|)

Answer 1

Try these commands:

1. di" (mnemonic: delete iniside ")
2. da" (mnemonic: delete around ")
3. di( or dib (mnemonic: delete inside () pair)

if you want to change the values (i.e. delete and remain in insert mode), use c instead of d.
