Once you get accustomed to these, they can be very useful for quickly performing certain commands without moving your hands from the "home" keyboard position. These shortcuts are not in fact provided by IPython itself, but through its dependency on the GNU Readline library: as such, some of the following shortcuts may differ depending on your system configuration.Īlso, while some of these shortcuts do work in the browser-based notebook, this section is primarily about shortcuts in the IPython shell.
The IPython shell doesn't go this far, but does provide a number of keyboard shortcuts for fast navigation while typing commands. Power-users tend to go even further: popular text editors like Emacs, Vim, and others provide users an incredible range of operations through intricate combinations of keystrokes. Most familiar perhaps are the Cmd-C and Cmd-V (or Ctrl-C and Ctrl-V) for copying and pasting in a wide variety of programs and systems. If you spend any amount of time on the computer, you've probably found a use for keyboard shortcuts in your workflow.
