Description

Summary

commands to leave normal mode, as well as those to leave insert mode, eg. Ctrl-[ suggested in #124 work fine for me on OS X browser. They do not work however on iPad browsers (Safari and Chrome). This seems to be an issue with the esc key not being there in iOS devices (see https://github.com/jupyter/notebook/issues/2378

I have installed vim-binding for Jupyter to fix my iOS issue. So far I am pretty happy with the vim-like experience I get on my mac, but it's so close to work on iPad that it's a real pity the esc button and all the possible substitutes I tried do not work.

Do you think jupyter-vim-binding can lead to a solution of this esc button issue on iOS?

Research direction
Investigate the keyboard event handling in the jupyter vim binding codebase, focusing on how the 'esc' key and its alternatives (like Ctrl [) are captured. Refer to the linked issue jupyter/notebook#2378 for known iOS keyboard limitations. Consider implementing a workaround for iOS by remapping 'esc' to a different key combination that is available on the iPad keyboard, such as Ctrl [ or another chord. Testing should be done on an actual iPad or iOS simulator to verify the fix.
