Load search URL in browser from Visual Studio

问题:

I'm finding the built-in Visual Studio Document Explorer less relevant, especially as more of the SDKs I work with have the most up-to-date content on-line. Pressing F1 starts Document Explorer usually with something unhelpful and it's not usable any more for me.

Is there any way that on the press of a key combination in Visual Studio:

• the default browser opens to the URL of a search engine
• query used is the keyword under the current cursor position
• a filter is added such as site:msdn.microsoft.com

I don't know anything about macros in VS but presumably that's what I need. Does anyone know how to go about setting this up? teh codez would be nice!

Here is another version (based on Alex's answer) that will also select the current word you are on. More like the typical F1 help.

Imports System
Imports EnvDTE
Imports EnvDTE80
Imports EnvDTE90
Imports System.Diagnostics

Public Module Search
    Sub GoogleSearch()
        AnySearch("http://www.google.com/search?q=.net+")
    End Sub

    Sub BingSearch()
        AnySearch("http://www.bing.com/search?q=")
    End Sub

    Private Sub AnySearch(ByVal searchUrl)
        Dim strUrl As String
        Dim selection As String = GetSelection()
        If selection <> "" Then
            strUrl = searchUrl + selection
            DTE.ExecuteCommand("nav", strUrl & " /ext")
        Else
            MsgBox("Select text to search for.")
        End If
    End Sub

    Private Function GetSelection() As String
        Dim selection As TextSelection = DTE.ActiveDocument.Selection()
        If selection.Text <> "" Then
            Return selection.Text
        Else
            DTE.ExecuteCommand("Edit.SelectCurrentWord")
            selection = DTE.ActiveDocument.Selection()
            Return selection.Text
        End If
    End Function
End Module

Using the link Preet provided I came up with this which starts the default browser:

Imports System
Imports EnvDTE
Imports EnvDTE80
Imports EnvDTE90
Imports System.Diagnostics

Public Module Search
    Sub GoogleSearch()
        AnySearch("http://www.google.com/search?q=")
    End Sub

    Sub BingSearch()
        AnySearch("http://www.bing.com/search?q=")
    End Sub

    Private Sub AnySearch(ByVal searchUrl)
        Dim strUrl As String
        Dim selection As TextSelection = DTE.ActiveDocument.Selection()
        If selection.Text <> "" Then
            strUrl = searchUrl + selection.Text
            DTE.ExecuteCommand("nav", strUrl & " /ext")
        Else
            MsgBox("Select text to search for.")
        End If
    End Sub
End Module

I've come up with this one. As it says, you will need to add a reference to 'System.Web' for HttpUtility.UrlEncode. Also, there's a few 'options' in the code commented out. Parts taken from http://www.codinghorror.com/blog/2005/10/google-search-vsnet-macro.html , but much improved (IMHO).

                Web.HttpUtility.UrlEncode(s))
            '--------------------------------------------------------------------------

            'You will need to add a reference to 'System.Web' for HttpUtility.UrlEncode !!!
