Not sure that would work everywhere but !$ definitely does for retrieving the last arg of the last command. 40 years of muscle memory right there

Alt + . is a readline binding, so that's available wherever GNU readline is used. Immediate examples that come to mind are Python PDB shell and GDB.

And thus you get vim modes there too much if you set your .inputrc for it !

Nobody mentions $_ ? It gives you the last argument used, so:

  cat filename.txt

  grep "what I want" $_

expands "$_" to "filename.txt"
