Micro is probably better at this point for such purpose. However I also have some customizations myself to use some kind of modeless commands to quickly select or move around, but I still model things around basic vim syntax and its fantastic move keys which keep me in the home all the time (e.g. Using alt+ghjk from insert, I move around, adding shit I select, without having to switch to move or visual mode)
