That's just playing with words. As far as we on this list are
concerned, your contribution to the thread was a process: editing
PostScript source text with vim. The work that you put into this
process/interface/call it what you will, was a lengthy session
of learning the PostScript language. That has to be costed in,
just as learning about snap-to-grid has to be.

The marks on the paper were not under discussion, neither as a
technical drawing nor as an architectural design, but only the
operations to produce them.

That's why I quoted it, so people could judge for themselves. It's
the one part of your process that can be clearly put in a posting.
This source code has to be mastered.

One would expect that of someone who sees using a mouse as fighting it.

But here we have no way of knowing how the OP views using a mouse
(which for most spreadsheet operations plays a minor role):
whether it makes things easier or speedier, or is best avoided.
For most people, there's a balance; they use both mouse and keyboard
as they feel is appropriate for each action.

All that said, the thrust of my post was: everyone should have some
sort of acquaintance with spreadsheets by the time they leave school.
Vim key bindings—perhaps not. PostScript—probably not.
