Vim quick way to change method arguments

Question

One of the most common source code operations is changing method arguments. Given a list of method arguments as follows:

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

I want to know how to handle the following operations (I use |here as the cursor position):

• When the cursor is inside the quotation marks, and you want to delete the contents inside the quotation marks. for example: "ar|gument1"to"|"
• same as the first, but remove the quotes.
• delete all things in brackets. ("argument1","argument2","argument3")before(|)

Answer 1

Try the following commands:

• di"(mnemonics: delete iniside ")
• da"(mnemonics: removal around ")
• di( dib (: () )
