How to enable mnemonics in 12.04 and/or 14.04 GTK3?
Solution 1:
Looks like GTK+-3 lost the "gtk-auto-mnemonics" setting after version 3.8 (starting from version 3.10 on).
The following patch for 3.14.4 should re-enable "gtk-auto-mnemonics". It will probably also work with other GTK+-3 versions like 3.16. After compiling, you'll only need these files (first two are symlinks):
libgtk-3.so -> libgtk-3.so.0.1400.4
libgtk-3.so.0 -> libgtk-3.so.0.1400.4
libgtk-3.so.0.1400.4
http://ftp.gnome.org/pub/gnome/sources/gtk+/3.14/gtk+-3.14.4.tar.xz
You can easily start using the compiled stuff by this (replace lib64 with lib if necessary):
LD_LIBRARY_PATH=/folder/where/you/installed/lib64 file-roller

Don't know why, but it looks like the GTK+ developers became really great in removing code which provided useful features like this...!!!
If any GTK+ developer reads this: How did those code-lines hurt anyone or why where they removed???
If someone's interested in the original commit:
- https://github.com/GNOME/gtk/commit/7e3a494fac62140f466fc43f6cc061215953e9b1
- https://github.com/GNOME/gtk/commit/7e3a494fac62140f466fc43f6cc061215953e9b1.patch
Looks like the GTK+ people had a feature-remove run at that time:

Solution 2:
To "disable" mnemonics for Nautilus 3.10.1 on Ubuntu 14.04 which uses GTK3:
- Create the following path & file if it doesn't already exist.
/home/YOURUSERNAME/.config/gtk-3.0/settings.ini - Then add:
[Settings]gtk-enable-mnemonics = 0 - Then logout and log back in.
Sources:
- Is there an equivalent to .gtkrc-2.0 in gtk 3? | GNOME Mail Services
- Settings: GTK+ 3 Reference Manual | GNOME Developer Center
p.s. Note that the GTK docs say you should have an environment variable called XDG_CONFIG_HOME but I didn't have one. I did have an existing ~/.config/gtk-3.0 folder and it appears it is looking there by default, without the environment variable.
Solution 3:
I think I was changing the wrong theme. Oops.
Steps followed.
https://stackoverflow.com/a/24095212/2026508
Change from: gtk-auto-mnemonics = 0 <---- Disabled
Change to: gtk-auto-mnemonics = 1 <---- Enabled
In GTK3 change in settings.ini:
/usr/share/themes/CURRENT_THEME_NAME/gtk3.0/settings.ini
In GTK2 change in gtkrc:
/usr/share/themes/CURRENT_THEME_NAME/gtk2.0/gtkrc
But make sure it is the correct/current theme.
