Keyboard shortcut conflict for Escape

[nthiery]

Description

When both in full-screen mode and edit mode, hitting esc is ambiguous:
exit the full-screen or switch to command mode.

Reproduce

1. Follow jupyterlab-rise's binder link
2. Slides switches automatcailly to full-screen mode
3. Press Enter or double clic on a cell to enter edit mode
4. Hit Escape
5. The slideshow exits full-screen mode

Expected behavior

Switch to command-mode

Discussion

The rationale is that Escape is used extensively when editing
notebooks, and thus hardcoded in the users's fingers, whereas escaping
full screen mode is done just now and then. One could still escape
full screen mode by typing Escape a second time.

However this could be a standard shortcut of browsers; in that case
it's annoying to break a convention. It could even be that browsers
would not allow to change this shortcut.

However this could be a standard shortcut of browsers; in that case it's annoying to break a convention. It could even be that browsers would not allow to change this shortcut.

It looks like a standard shortcut for browsers. I've been looking for a solution, and no one recommends intercepting the Escape key event to prevent the browser to exit the full screen. Nevertheless, it must be possible to implement because there are multiple web apps that do it, but I could not find the solution.

We advice users to make use of the alternative shortcut Ctrl+M to exit edit mode.

Thanks @hbcarlos and @fcollonval for investigating and for the workaround!

This remains rather annoying because
Escape to exit edit mode is quite hard-wired in the fingers of notebook users, and discovering
Ctrl-M is not obvious.
