Can we document these in the readline doc? While a TTY is required for most of these, they shouldonly affect readline behaviour

I guess it would be fine to add a reference to those in the repl

@shobhitchittora Yes, that’s the idea (although I don’t really understand why this would be added to the TTY
doc)

@addaleax I saw this code in readline -
Interface.prototype.write = function(d, key) {
if (this.paused) this.resume();
this.terminal ? this._ttyWrite(d, key) : this._normalWrite(d);
};
and thought that TTY case need a doc. But yeah we can have the table in readline
doc and ref it in REPL
and / or TTY
.
Need you opinion on this.

Yeah, exactly – it’s code in readline. :) We should point out that these codes apply only for TTYs, but it’s not something that’s interesting for code that uses TTYs in general.

@addaleax you are right, the TTY docs are actually the wrong place for this. The repl
should have a reference however.

@vsemozhetbyt I think it'd be great if we can do that. Unfortunately I don't have a windows system and cannot verify bindings for the same. All help is appreciated. 😇 |

LGTM with the whitespace removed. My two comments would also be nice but I think that could also be done later on (even though I would prefer to have it that way right away).
