The above works for tcsh's simulated NLS and for -the NLS in SunOS 4.1 - without the NOREBIND setting, all of the -Meta-<non-control-character> bindings would be undone in these cases. - -.pp -These keybindings are the codes for my national characters, but the bindings -(M-d, M-e etc) are not conveniently placed. -They are however consistent with what other programs will see. - -.pp -Now: I actually want the character \\304 to be inserted when I press say '{' -together with a modifier key.
