Answer 1

Based on a few of the SO's around this matter (see my comment in the @mb14 answer here), I was thinking of muscle-memorizing something like this:

di(a[]P

but what I really wanted to do was this:

di(c%[]P

You will see that you cannot do that because the c puts the () brackets into your 0 register and therefore you actually need to do this:

di("_c%[]P

or (I was also trying out a 'yank' approach and came up with) this:

yi(ca([]"0P

Okay, neither is too bad, but it occurred to me that this is going to all go much better if I map c to "_c so that I have a real delete and can do this:

di(\c%[]P

or this:

yi(\ca([]P

Both are pretty close to what I wanted to do, and the thought process has given me one of the most valuable lines in my $MYVIMRC:

noremap c "_c
