Feature request: fastwarp for left parenthesis

[arielherself]

Thanks for the great plugin! I often found that an extra pair of parenthesis need to be added for a previous expression when writing code. Therefore, I would really appreciate it if such a feature is implemented:

test(|) > (|test)

It is basically like the fastwarp and rfastwarp feature, but for the left parenthesis. Thanks for your effort!
