[Evolution] keyboard shortcut for "view all [attached photos] inline"

[Herr Oswald <herr_oswald gmx de>]

Hello,

I tried to add a keyboard shortcut for "view all [attached photos]
inline" by changing line 87 in ~/.config/evolution/accels to

(gtk_accel_path "<Actions>/e-mail-display-attachment-inline/show-all"
"F8")

but that does not work. Does someone have a better idea?

Cheers,
Wolf
