Shortcuts
For Ubuntu's default keybinding settings (i.e Emacs keybindings)
Insert previous arguments
- Alt+.: insert last argument from last command.
- Alt+number+.: insert #nth last argument from last command.
- Alt+- , number , Alt+., zsh: Alt+-+#+.: insert #nth first argument from last command.
In Linux you can repeat commands to go back in history
Example:
Last command is:
mv foo bar
- Alt+0+.: insert first argument of last command =
mv - Alt+2+.: insert last 2nd argument of last command =
foo - up , Ctrl+w: last command without the last word =
mv foo
Cut/Paste commands
(relative to cursor's position)
- Ctrl+w: cuts last word
- Alt+d: cuts next word
- Ctrl+k: cuts everything after
- Ctrl+u, zsh: Alt+w: cuts everything before
- zsh: Ctrl+u: cuts the entire command (In bash you can combine Ctrl+u , Ctrl+k)
- Ctrl+y: paste characters previously cut with any Cut command. In bash you can chain cut commands, and Ctrl+y will paste them all.
Move cursor
- Ctrl+left: move to last word
- Ctrl+right: move to next word
- home or Ctrl+a: move to start of command
- end or Ctrl+e: move to end of command
Other
- Ctrl+_: undo last edit (very useful when exceeding Ctrl+w)
To see all shortcuts available

Common usecases
Let's consider the last command to be:
mv foo bar
up , Ctrl+w: last command without the last word = mv foo
Alt+0+.: first argument of last command = mv
Limitations
"words" only includes a-zA-Z characters, so any symbol character will stop word-shortcuts.
So if last argument was a url and you want to erase it with Ctrl+w it will be a pain.
E.g: curl -I --header "Connection: Keep-Alive" https://stackoverflow.com/questions/38176514/re-run-previous-command-with-different-arguments
To erase that url using Ctrl+w, you'd have to repeat it 12 times.
It would be great to have similar shortcuts that only stops at the space character
