wasn’t a mouthful like MoveFromPosition

PosMove, but nothing wrong with MoveFromPosition either.

I also easily get annoyed by mouthful typing, so I usually do the following: write code in short identifiers and then rename them after I finish.

I wish dev envs could store two representations for an identifier, one short and one long, so one could easily switch between these (and also local/personal ones, or name comments at least). But that’s rocket science for text-based sources.
