[9fans] acme cut/paste chords

[Eoghan Sherry]

greetings 9fans,

i've been working on the cut/paste chords in acme (1down 2click 3click
doesn't work in tags in the plan9port version) and have discovered an
oddity. performing 1d 2c 3c in a body results in a cut followed
by an undo, thus preventing the body from being marked as dirty. similarly,
performing a 1d 3c 2c results in a paste followed by an undo. however,
the inverse of pasting over selected text is not a cut; it is restoration
of the original text. this seems inconsistent with the basic cut chord (1d 2c)
and i'd like to change the meaning of 1d 3c 2c to be a paste followed by a cut.

i realize this is a minor point (has anyone ever used a 1d 3c 2c chord?), but
does anyone have an opinion on the matter?

Your oddities are my helpful mechanisms.

I use 1-3-2 when I accidentally 1-3.  It's undo,
just like 1-2-3 is undo.

The fact that undo for 1-3-2 is broken in tags 
doesn't mean that it should be broken in the bodies.

thanks for the responses.

my motivation was to make 1-3-2 in bodies consistent with
tags and rio behaviour. given that some rely on the undo
behaviour, i'll look at extending it to tags.

better would be the other way around (make rio more
like acme). it's quite deliberate that the two chords are
inverses. from the man page:

          Several operations are bound to multiple-button actions.
          After selecting text, with button 1 still down, pressing
          button 2 executes Cut and button 3 executes Paste.  After
          clicking one button, the other undoes the first; thus (while
          holding down button 1) 2 followed by 3 is a Snarf that
          leaves the file undirtied; 3 followed by 2 is a no-op.

mind you, there is still some odd behaviour in there that i've been
unable to reproduce consistently - trying this out, several times i
managed to get to a situation where the file was changed within acme,
but an Undo wouldn't get me out of it.
