Yes, but that's more of an issue with the
terminal emulator. I mean use Escape instead of
Meta in the physical, keyboard sense.

    xterm*metaSendsEscape: true

Here is how to disable caps and do something
else with it in X:

    setxkbmap -option caps:none  # disable caps lock
    xmodmap -e 'keycode 66=a'    # rebind CAPS (66)

Right, it is a good pick for Meta.

The current standard for what? The Escape key
on that keyboard isn't current, it is much
closer which is probably why it was more
popular for this purpose on those keyboards.
The arrow set (h, j, k, l) is close to there
right hand, but somewhat unintuitive with ups
and downs, or at least not as intuitive as it
could be.

I think the arrow keys are best placed as:

          i = up
j = left  k = down  l = right

My first computer was a Mac Plus and the games
there, like Lode Runner, this was used - for
Dark Castle it was correspondingly w, a, s,
d because with the right hand, one aimed the
rock throwing arm with the mouse.
This reappeared much later in 3D games such as
Quake btw.

Anyway I think the i, j, k, l set is the best
at is is close and intuitive. In many
applications, e.g. for viewing images and PDF
documents, I have implemented it, and in Emacs
I use it for Emacs-w3m, scrolling [1], and
so on.


Ha! I can't see anything on that photo.
Where are the Escape and arrow keys?!
