972534 - CodeMirror vim / emacs keybindings should not trigger other DevTools shortcuts

Status: NEW

(DevTools :: Source Editor, defect)

Description

[Brian Grinstead [:bgrins]]

As reported in hacks post (see URL), the vim keybindings conflict with some devtools keys:

* Escape while editing HTML in the inspector leaves the HTML edit mode instead of Vim’s insert mode
* Ctrl+] shortcut to switch between panels is swallowed by the Style Editor.

I'm thinking the escape key in 'edit as html' situation could be solved by stopping propagation of an event if the special keybindings have handled it.  Not sure if the Ctrl+] is not being handled by the keybindings, or if somehow the panel switching is overriding it.

In vim mode it's also hard to do cut/copy/paste operations...

The editor is basically unusable while this bug exists, at least for the vim bindings.

Should we hide and ignore the pref until this bug is resolved?

In the Style Editor, you can use Ctrl+C to exit Insert mode, in both the Linux and OS X versions. Ctrl+[ does indeed break out of Insert mode on the OS X version (as it uses uses Cmd+[ for switching panels, not Ctrl).

Standard shortcuts – such as copy/paste and Scratchpad's Run/Inspect/Display/Pretty Print etc do indeed work in Insert mode. Would we want them to work in Normal mode? I would expect conflicts to arise easily. 

However, the Debugger's shortcuts override Vim keybindings, making it nearly unusable in Normal mode even.
