In my shell (zsh) or in python, I can go backward through command history by pressing PageDown, and I can go forward by pressing PageUp.
But in ipython, these shortcuts are reversed.
Where are these shortcuts defined for ipython, and how can I reverse them back, so that
PageDown goes back in history, and PageUp goes forward in history?
I am using ipython3 version 5.8.0 on Debian 10.
Create script in ~/.ipython/profile_default/startup directory with any name ending with extension .py or .ipy
For example i created history_keybindings.py and put it inside ~/.ipython/profile_default/startup directory
from IPython import get_ipython
from IPython.terminal.shortcuts import previous_history_or_previous_completion, next_history_or_next_completion
from prompt_toolkit.keys import Keys
from prompt_toolkit.filters import HasSelection
ip = get_ipython()
registry = None
if (getattr(ip, 'pt_app', None)):
# for IPython versions 7.x
registry = ip.pt_app.key_bindings
elif (getattr(ip, 'pt_cli', None)):
# for IPython versions 5.x
registry = ip.pt_cli.application.key_bindings_registry
if registry:
registry.add_binding(Keys.PageUp, filter=(~HasSelection()))(previous_history_or_previous_completion)
registry.add_binding(Keys.PageDown, filter=(~HasSelection()))(next_history_or_next_completion)
