Next question, do you usually add stuff to buffers in alphabetical order... a,b,c or do you pick something easier within reach like a,s,d (or something else entirely)
To really blow your mind:
i<c-r>%
V:!ls<cr>
It's again, esoteric, but as you use it more, it becomes less esoteric and more just another part of your vim vocabulary (:help search-offset, fellow traveler).
