I am using vim to edit a shell script (did not use the right coding standard). I need to change all of my variables from camel-hum-notation startTime to caps-and-underscore-notation START_TIME.

I do not want to change the way method names are represented.

I was thinking one way to do this would be to write a function and map it to a key. The function could do something like generating this on the command line:

s/<word under cursor>/<leave cursor here to type what to replace with>

I think that this function could be applyable to other situations which would be handy. Two questions:

Question 1: How would I go about creating that function.

• I have created functions in vim before the biggest thing I am clueless about is how to capture movement. Ie if you press dw in vim it will delete the rest of a word. How do you capture that?
• Also can you leave an uncompleted command on the vim command line?

Question 2: Got a better solution for me? How would you approach this task?
