Quick tip: If you do the majority of your typing in Emacs, it can feel gratingly clumsy to type anywhere else, like in browser text fields and IM windows.
I discovered today that GTK has an option to enable common Emacs editing keys in text fields everywhere on your system. This is amazing–it means no browser extensions or hacks are needed to type over four lines without cursing.
The setting is buried at ‘desktop/gnome/interface/gtk-key-theme’ in the gconf-editor; change its value to “Emacs”, or paste this in a terminal:
gconftool-2 --set /desktop/gnome/interface/gtk_key_theme Emacs --type string
Most common navigation and editing keys work just as they do in terminal emulators:
The CUA keys
C-v continue to cut, copy and paste respectively.
