/* Persistent mnemonics:
* (from 'sgm-flexible-mnemonics.c' [https://github.com/thesquash/sgm])
*
* Restores the behaviour of the GTK setting 'gtk-auto-mnemonics'. When this
* setting is set (TRUE, the default), mnemonic letters on buttons and menu
* items will be underlined only while the <Alt> key is pressed; when unset
* (FALSE), mnemonics will always be underlined.
*
* Enable the latter behaviour by adding to your settings.ini file:
*
* gtk-auto-mnemonics = 0
