By default, when you type text into the Find/Command box and press ENTER, it searches for the text in the current document or window using the search and replace options specified in the Find and Replace Window. For more information, see Finding and Replacing.

You can also use certain key combinations with the Find/Command box.

When you search from the Find/Command box, the Find Results 1 window appears, displaying the current search settings. If, for example, the last time you searched from the Quick Find, Find and Replace Window, you selected the Match case option, the Find Results 1 window would display

Find "mybutton", Match case, Current document

To use the Find/Command box to issue a single Visual Studio command or alias rather than search for text, enter the Visual Studio command, prefaced with a greater than (>) symbol. For example:

>File.NewFile c:\temp\MyFile /t:"General\Text File"

Alternatively, you can also use the Command window to enter and execute single or multiple commands. Some commands or aliases can be entered and executed by themselves; others have required arguments in their syntax. For a list of commands, see Visual Studio Commands and Switches. For a list of commands that have arguments, see Visual Studio Commands with Arguments.

A caret (^) character in a command line means that the character immediately following it is interpreted literally, rather than as a control character. This can be used to embed straight quotation marks ("), spaces, leading slashes, carets, or any other literal characters in a parameter or switch value, with the exception of switch names. For example,

>Edit.Find ^^t /regex

A caret functions the same whether it is inside or outside quotation marks. If a caret is the last character on the line, it is ignored.
