Console go-to-line shortcut causes error on firefox with 'escape'

[dakrone]

Kibana version: 5.0.0-RC1 (though it also occurs in 4.6.1)

Elasticsearch version: 2.4.1 & 5.0.0-RC1

Server OS version: Fedora 24, kernel 4.7.7-200.fc24.x86_64 #1 SMP

Browser version: Firefox 49.0

Browser OS version: Fedora 24, kernel 4.7.7-200.fc24.x86_64 #1 SMP

Original install method (e.g. download page, yum, from source, etc.): Tarball download

Description of the problem including expected versus actual behavior:

Hitting ctrl-l in console pops open a dialog to go to a specific line:

When someone hits escape on this dialog box (to clear it if it was unintended), they are taken to this screen:

With this error:

Error: uncaught exception: unknown (can't convert to string) (:0)
window.onerror@http://127.0.0.1:5601/bundles/commons.bundle.js?v=14361:69:13503

There is another problem here, Ctrl-l is a common browser shortcut for all browsers on Linux, to focus the address bar. To overwrite it with no way of disabling this is unfortunate. See @ycombinator's comment here: #4539 (comment) about unfortunate keyboard shortcuts doing unintended things.

I don't think ctrl-l should be overwritten without a way to turn the shortcut off.

I can't reproduce this bug on master, so I'm going to close this issue. I've opened #48410 to capture the need for disabling the keyboard shortcuts.
