That is strange. Starting ved, pressing ENTER and then "teach teach"
I see the teach file. I get error as you describe when teach
files are not present. But then what you do below would not
work...

1) 'teach' command really is ved that knows where to look for
teach files (so there is no need to give full pathname) and
which protects orignal from modification (so you can play
with a file without fear of destroying useful info)
2) before using ved you definitely should look at
'pop/help/linuxterm', it explains keys on PC keyboard.
Modern keyboards (especially laptop keyboards) have
various slightly different layouts, but typically keys
with the same description (marking) on newer keyboards
do the same things as keys with the same description on
older keyboard. So if you know where the key is on older
keyboard you can find out what function it has. Playing
a little with ved (possibly using teach file) should
clarify doubts.

Ved keybinding are somewhat strange. Hope that the above and
what Steve wrote helps. You did not wrote which version
you fetched. Assuming that this is V16, there is a change:
teach and ref are not provided as separate shell commands.
As distributed one needs to start them from ved or pop11.
That could be easily changed assuming that teach in ved
works: one just needs to do:
ln basepop11 teach
in the pop/pop subdirectory of Poplog tree (and similar for
ref command). However, if 'teach teach' does not work
from ved or pop11, then link will not help.
As I wrote, error message that you gave appears when teach
files are not present, or in wrong place (that is why Steve
asked about '$usepop/pop/teach/teachfiles'). You wrote
that file is where it should be. In such case it remains
a mystery why ved can not open it via 'teach'. Does it
work if you try to open copy of 'usepop/pop/teach/teach'
in ved?
