User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:18.0) Gecko/20100101 Firefox/18.0 Build ID: 20130117041235 Steps to reproduce: I've got include "/usr/share/themes/Emacs/gtk-2.0-key/gtkrc" in my ~/.gtkrc-2.0. Actual results: While C-k ("kill-line") works in Firefox --- N.B., this is only after installing version 0.1 of the Change Search Shortcut (Cf. https://addons.mozilla.org/en-us/firefox/addon/change-search-shortcut/ and https://addons.mozilla.org/en-us/firefox/addon/change-search-shortcut/versions/) --- C-y ("yank") does not work. Expected results: KeySnail provides this functionality, but it doesn't work on recent versions of Firefox. ("KeySnail provides multiple clipboards to the Firefox. Press C-y to yank and M-y to yank pop. C-M-y allows you to list and insert items in kill ring.", from https://github.com/mooz/keysnail/wiki) My sense is that C-y should be built in. Presumably this part applies at the GTK 2.0-level issue, but since I noticed it first/only in Firefox, I'm starting by reporting it here. To explain some Firefox-specific aspects of this bug report, I'll also mention: in order to make M-b ("backward-word") and M-f ("forward-word") work, I had to remove *B*ookmarks and *F*ile from the menu. The point being, Firefox doesn't really respect Emacs keys without a lot of user configuration, and the existing set of built in functionality is not broad enough.
