You're doing the right thing but you need to hold down the "Tilde" key to keep the connected stuff where it is while you make your edit..
On my (UK) keyboard, the tilde key is between the left shift key and the Z - but I believe on some it's next to the escape key - it's symbol is a horizontal wavy line. If you can't find it, I'm sure you can Google it.
Spot-on, andynick. That's exactly what I needed. Thanks so much. So apparently I just worked around it before. This surprises me because with this current edit I'm working on I'm running into it a lot and it was driving me nuts. Wonder why it didn't bother me before?
And, yes, I'm well familiar with the tilde. Can't spell "habañeros" without it!
