Similar to ALT-. which is introducing the last argument verbatim.

But what I was really longing for is a variable or hotkey producing the last output , alas this doesn't exist.

The closest I could find now is `!!` , I.e. to backtick the last command.

But I'd really love to facilitate this be defining a shortcut introducing `!!` ...

So I figured out bind '"\e,":"`!!`"' (ESC for ALT) which also works well on termux.

Put it into your bashrc and it'll help you to incrementally build one liners.

Dumb example:

$ bind '"\e,":"`!!`"'
$ ls *re.pl
tst_re.pl
$ echo `!!`        # typed "echo ALT-,"
echo `ls *re.pl`   # expanded history entry
tst_re.pl
$

Update

This will nest better when used repeatedly 

$ bind '"\e,":"$(!!)"'
