Enlarging System-Wide Theme / Font in GTK Settings

I'm in my 70's and prefer a larger theme and font than the BL default settings. This method is probably obvious to many users, but I wasn't aware of how to do it until recently.  It's actually very easy. I used the following settings to get the perfect result (for me).

It's a good idea to create a backup of the .config file before experimenting with changes.

ben@boron:~$ nano ~/.config/gtk-3.0/settings.ini

1 [Settings]
2 gtk-theme-name=Boron-aqua
3 gtk-icon-theme-name=Numix-Bunsen-Circle-aqua
4 gtk-font-name=Sans 12  # Changed from 10 to 12
5 gtk-cursor-theme-name=DMZ-White
6 gtk-cursor-theme-size=24  # More reasonable cursor size
7 gtk-toolbar-style=GTK_TOOLBAR_ICONS
8 gtk-toolbar-icon-size=GTK_ICON_SIZE_LARGE_TOOLBAR  # Changed from SMALL

Menu > User Settings > Appearance also give you a GUI for changing most of these.

^ Don't forget the freaking eight (? at least 6) font choices in obconf. Font size for jgmenu is also independent.

I don't care what you do at home. Would you care to explain?

Doh! Should've known you guys would provide a means to do this with the GUI.
