     11so there is this old_esc_mode option ... 
     12it really needs some more exposure. in fact, it should be enabled  
     13by default, and the timeout should be lowered from one second to at  
     14most 100 ms (that is, virtually instantaneous). 
     15high-latency network links should not cause problems, as the chars  
     16of one keypress should still be in one packet, keeping the sequence  
     17intact. if there really is some problem with this, the patch posted

     19via an environment variable can be used.

    13 I'd like to be able to set it to 0 ms, i.e. Escape behaving as  
    14 Escape and nothing else.

     30first a correction on my side: meanwhile i did actually experience  
     31a sequence being torn apart, so the "one packet" theory simply does

     33going slightly overboard, one could apply some heuristics to  
     34determine the worst-case line latency automatically.

     36i'm not sure it is a good idea to make the timeout a proper option  
     37only. it makes sense to have the setting depend on the location, or  
     38rather on the route to the location. an env variable seems to be  
     39the by far the most appropriate means of achieving this. having  
     40separate settings for certain $TERM seems interesting as well, as i  
     41might want to extend the timeout for terms where i have to enter  
     42esc sequences manually - but that can be scripted in the startup  
     43script as well. 
     44other than that the patch seems reasonable (i did not test it, but  
     45i don't see any code paths which you could have skipped if you  
     46tested it at all ;).

    27 you can log into the same machine from different sources - locally,  
    28 through serial line, through networks with different latencies. and  
    29 also you can share the same config among several machines if you  
    30 have a networked home. both cases are not exactly exceptional in  
    31 heterogenous environments like unis or even when simply ssh-ing  
    32 into your box at home. 
     61this is slow. and extremely annoying if done several times a day.

    44 i think the env var should override the setting, but both make  
    45 sense. ideally, the config dialog would show whether the setting  
    46 will take effect - to avoid surprises.

     71it is scriptable. without sed-ing the config file, that is. 
     72in the scenarios i drafted this option is rather imposed by the  
     73operation environment than by user preference, so it just makes  
     74sense to use something that is naturally part of the environment.
