Week 1 of my vim productivity boosting experiment went well. During the week most of the commands I aimed for ended up being used often.
I got a lot of helpful comments, both here and on Hacker News. I ended up unmapping my arrow keys, and I do feel like this made a difference, I am now comfortable with those keys. As a bonus, it feels a lot more natural using hjkl in compound movement commands than it did with the arrow keys.
This week I will focus on repeating previously issued commands. Since 4 at a time worked well for me last time, I will stick to that number.

For next week I will go through the comments and pick the ones I found most useful in there.
