Solved Repetative audio correction

I have a long audio that has a repetative correction needed to be fixed.  The narrator says the word "So" way to many times   So... (lol) here is my list of repetative steps: 
1. Highlight the area around "so" 
2. Mute the highlighted area
3. fade out dialogue before the muted "so"
4. fade in dialogue after the muted "so"
I would think there would be a solution for this already, but I have no idea what to ask for or what this is called.  I have done a quick search here, but I don't even know what I am looking for, so...can someone help?  TIA

That is hilarious, because you have just described what I often have to do after I record my own tutorials.
I am guilty of getting "So" stuck on brain repeat.

I don't know of any automated way to do this, however this is the fastest way I have developed.
1. Turn on Audio Volume Envelope tool for voice track. Shift + V is the keyboard shortcut to activate it.
2. Zoom into the timeline (scroll wheel on mouse) so you can edit words out.
3. When you find a "so", drag a loop region around the area you want to mute just above the Timeline Ruler.
4. You can now drag the Volume Envelope line down between the loop region points - this will automatically create key-frame points to mute the "so".

Thanks Derek, great tip I did not know "3. When you find a "so", drag a loop region around the area you want to mute just above the Timeline Ruler."
Personally I prefer to hit the mute button rather than drag the volume envelope down, I find it faster.  Another word, I hear in Canada, far too often is "Like"
