A classification of indexcard by
project is tiny tiny matter. It takes only few second in time
maybe. But it incredibly reduced number of indexcard I write.
Same is true for text editor on computer. I do love to use Vim for programming. The Vim
(or just vi) enables to move line to line only with keyboard. It
helps to connect thinking and writing, brain and hand more
seamlessly. I also use TextMate because of it's friendly interface and useful
templates. If I use it for programming, however, I feel I don't
want to write program anymore with TextMate. This is not due to
TextMate, of course, but I'm just frustrated every moment I use
mouse.
Difference between using mouse or not may be less than a second in
time, and few tens of centimeter in distance. This sounds really
tiny matter. But my subconscious honestly react for it.
