Almost. tmux recognises this as M-b: keys are 2 (^[b) complete key ^[b 0x2062 writing key 0x2062 0x2062 is 0x2000 (Meta) + 0x62 (b). It isn't sent as-is (there is still a translate step), it just has that effect. > > When TERM is 'nsterm': > 1. tmux receives an \Eb from the terminal > 2. tmux notices that \Eb is kLFT3 (Alt+Left) in terminfo > 3. tmux translates Alt+Left into KEYC_LEFT|KEYC_ESCAPE (tty-keys.c) > 4. tmux KEYC_LEFT is ^[[D or ^[OD, depending on the mode > 5. tmux sends KEYC_LEFT|KEYC_ESCAPE to the application Yes this is right. > Makes perfect sense.

This doesn't seem to be the case, from your logs: keys are 2 (^[b) complete key ^[b 0x301f writing key 0x301f found key 0x301f: "^[[D" This shows tmux found ^[[D for 0x1f (the key is looked for without the modifiers). Then: input_parse: '^' ground input_parse: '[' ground input_parse: '^' ground input_parse: '[' ground input_parse: '[' ground input_parse: 'D' ground input_parse is logging what tmux receives from the terminal, in this case it is "cat" printing "^[^[[D". So the additional ^[ was sent to the terminal, and cat echoed it. ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ tmux-users mailing list tmux-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/tmux-users
