Case switching

I have a bad habit of hitting the CapsLock key and when I type code, the shift key does the opposite, so instead of typing m_bSomeVariable, I will look up and see that I have typed M_BsOMEvARIABLE. DevStudio provides <Shift><U> and <Ctrl><Shift><U> to lower and upper case a selection, but nothing provides a "SwapCase" function. The following macro will do the swap. I assigned it to <Alt><U>, but that is entirely up to you ....


Sub SwapCase()
	' DESCRIPTION: Macro to swap the case of selected words.

	str = ActiveDocument.Selection.Text
	str1 = ""
	i = 1
	Do While (i < Len(str)+1)
		If (Mid(str, i, 1) = LCase(Mid(str, i, 1))) Then
			str1 = str1 + UCase(Mid(str, i, 1))
		Else
		str1 = str1 + LCase(Mid(str, i, 1))
		End If
		i = i + 1
	Loop
	ActiveDocument.Selection.Text = str1
End Sub
