 |Yes, this surprised me too. This test is true if $___SHRC is undefined,

It is also all the bugs everywhere; if a shell does not dig the
"there has been meat" then it may vanish to nothing, as in other
contexts it even has to

  #?0|kent:tmp$ i=i j=\ s; echo a $i${j} b
  a i s b
  #?0|kent:tmp$ i= j=\ s; echo a $i${j} b
  a s b

Thanks for this.  Yes, i had not understood this shall end up as
the : no-op in the end.  (Even more bogus given that kre@ at times
persuaded me to use "while :;" etc loops instead of "while true;"
etc, so .. i failed.)

 |Heh. I had to do the same on one of my old laptops; except a lot more keys

 |
 |```
 |$ cat /mnt/bak/sdf/tmp/nbsd/qey.sh 
 |#!/bin/sh

 |wsconsctl -w encoding=us.swapctrlcaps

 |done <<\EoF
 |keycode 1 = grave asciitilde
 |keycode 14 = BackSpace
 |keycode 211 = KP_Delete
 |keycode 41 = Escape
 |keycode 24 = o O i I
 |keycode 31 = s S a A
 |keycode 33 = f F d D
 |keycode 35 = h H g G
 |keycode 38 = l L k K
 |keycode 49 = n N m M
 |keycode 52 = period greater slash question
 |keycode 219 = Mode_switch

 |You produce the broken keys using Win+adjacent-to-broken key.

These are quite a lot..  But it is surprising how naturally it
became.  Here in the jungle every little piece wants extra
config.

There you go.  In general i am always happy when i have setup a VM
and go via ssh, so often SDL keymap was/is wrong (especially EFI
/ boot), and VNC i even no longer use at all because you surely be
unable to use some things.
