The [GNU APL documentation][1] on the line editor seems to assume one already knows how to use it. I only see brief mention of what commands/syntax '... are not fully supported in GNU APL'.
I looked through the SVN trunk's various README- files and in doc/, but not exhaustively so my apologies if I missed the obvious. Compare with the documentation of [Dyalog's APL ∇-editor][2], or [MicroAPL][3]. A succinct table of command syntax would be extremely useful to APL newcomers. I'd be willing to prepare a patch to submit for the documentation if someone can point me to more resources. (Related question: can GNU APL spawn an external editor specified by the user and use its resultant buffer as input? While nice, I'd still like to add documentation for the built-in editor).
