selects a range of characters delimited by double quotes.
i: select inside the delimiters.(inside)a: select everything including the delimiters.(around/all)
Note:
Text objects are not motions themselves: we can not use them to navigate around the document. we can use them in Visual mode and in Operator-Pending mode.
Remember this: whenever you see {motion} as part of the syntax for a command, you can also use a text object. Common examples include d{motion}, c{motion}, y{motion}.
ci": change inside the double quotes.cit: change inside the tag.yit: yank the text from inside the tag.dit: delete the text from inside the tag.
