doing completion and menu-completion with just one key

[Ernest Adrogué]

Hi there,

This is not a bug per se, just an idea.

On many occasions I find myself repeatedly typing a character followed by
TAB in order to narrow down possible completions, until there is just one
candidate left.  This is not efficient, because when there are just 3-4
possible completions it would be more convienent to simply cycle through all
completions like menu-completion does.  On the other hand, using
menu-completion is inefficient when the number of possible completions is
high.

One solution is first use completion to narrow down completions and in the
end use menu-completion, but I think it would be much better to use just one
key.  In my opinion the best solution would be this: the first TAB does
completion and successive TABs do menu-completion.  Currently I don't think
it is possible to configure Readline to do this, is it?

Regards.
