#Tip51: Trace Your Selection with Precision Text Objects

##Text Objects

define regions of text by structure. It allow us to operate on the regions of text that they delimit.

##vi}

Vim initiates Visual mode and then selects all of the characters contained by the {} braces.
Where the cursor is positioned to begin with doesn't matter so long as it's located somewhere inside a block of curly braces when the i} text object is invoked.

##a"

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.
