<p> When I first started using uEmacs, one of the most confusing things was the fact that the adaptation had not been entirely completed, or at least on my platform (an Atari ST), the keyboard mappings were not entirely idiomatic—they hadn&#39;t kept up with the differences between VT-100-style keyboards and, well, everything else.</p> <p> I think this explains why I got very habituated to the alphabetic keys for deleting stuff, but don&#39;t have the non-alphabetic keys as deeply ingrained.</p>
