Note that "last chosen" is not quite the hack you think it is.
It has a very desirable user-interface property.  On the average,
you end up moving the mouse up about half the time, and down
half the time.  This keeps the mouse on your desk.  By contrast,
using J. Random X utility, you continually drift off the bottom,
and have to lift the mouse up and recenter it on your desk.
Repeatedly selecting the same item in a pie menu (imagine a
"page forward" command in ghostview, for example) would still
exhibit this drifting property.  So you'd still want some sort
of "last chosen" default.

Mike is dead right.  "Last chosen" is abolutely not a `hack.'  I'd
be pleased if Mr Fitzhardinge was a little more careful with his
epithet-slinging.  Not only does it keep the mouse in the same
place on the table, but it also happens to contribute greatly
to the editor's usability, since a single click on B2 repeats
the last B2 action, which is often just what you want for
searching and pasting.

Hear, hear!  You want it?  You do it.

OK,

Pie menus

[Jeremy Fitzhardinge]

I've just been playing around with Don Hopkins' version of twm with pie
menus, and I think I really like them.

It struck me that they would be really useful to implement sam's menus
as a pie menu, especially the middle button cut'n'paste menu.  With a
small number of options, you can easily and accurately move the mouse in
the right direction to select things without having to read the label -
much more easily than moving down a linear menu.  Also, it's much faster,
since the mouse pointer starts in the right place for all the menu items,
rather than having the "last chosen" hack currently used.
