+Helper programs
+---------------
+The F3 and F4 keys are normally bound to actions 'view' and 'edit', similarly to
+Norton Commander and other orthodox file managers. The helper programs used
+here may be changed by setting the PAGER and VISUAL (or EDITOR) environment
+variables.
+
+While it is mostly possible to get 'mcview' working using an invocation like
+`PAGER='mcview -u' sdn`, beware that this helper cannot read files from its
+standard input, nor does it enable overstrike processing by default (F9, could
+be hacked around in 'mc.ext' by turning on the `nroff` switch for a custom file
+extension, just without actually invoking 'nroff'), and thus it can't show the
+program help. 'sdn' is currently optimised for 'less' as the pager.
