I was using a program called Goldwave to prepare a library of various
frog croaks.  It drove me nearly nuts.  To load the source file I had
to navigate through 7 jumps to get to the correct directory.  I would
process the file clipping it, then I had to navigate though another 7
directories to get to the target directory to save it.  Then back
another seven jumps to get to the directory for another source file.

I know, I could have loaded up more than one at a time, but this is a
general problem, in all computer OSes because the problem is inherited
from the structure of English.

In English there is only one HE pronoun. You can't talk about he1 and
he2.  In windows there is only one current directory. There is not a
source and target directory or a dir1, dir2 and dir3 button every
where available to jump directly to some other common place.

In English you can reassign the meaning of HE at any  without great
fuss.  It should be similarly easy in the OS. You just Right click on
of he the "pronoun" buttons to say -- from now on, this button means
HERE -- this directory, this file, this place in the file, whenever I
left click it, take me here.

This needs to be a function universally supported in the same way in
every application.

I use Slick Edit that lets me roughly approximate this, at least
within the Slick Edit universe.  I have some icons on the top bar I
can assign to macros. The problem is, to reassign the meaning of a
key, I have to compose a new macro, and go through a multikeystroke
sequence to assign the macro to the key.  But from then on I can hop
from place to place with a single click. What is missing is easy way
to assign a PLACE to a button with a single click.

Perhaps as an addition there could be history of places you visited
(not counting the places you just passed through) so you can point and
click to recently visited other spots.

Why am I telling you this.  Perhaps someone might like to write a
simple directory file/browser launcher, copier, deleter, renamer, much
like the old QDOS, that demonstrated the notion, perhaps evolving into
a Magellan-like tool with rapid file viewers.  I would be nice to get
back to as good as it was under DOS.
