- src/menu contains files for each menu's definitions.
- src/menu/transient contains menus which are reused in
many places or are separate from Main Menu entirely.
File names ending in "-1" are menus which contain
a submenu. The suffix is added so that the parent menu
sorts before all its children in directory lists.
It's also done so Tab completion doesn't stop such that
a hyphen (-) would need to be typed.
For example (this is how I auto complete file names):
"ex" <TAB> completes to "extras" because the choices are
"extras.c" or "extras-addons.c" etc. Now you need to reach
away from the home row of a keyboard to type a "-" in
order to complete any of the submenu file names.
VS
"ex" <TAB> completes to "extras-". You only need to reach
to type a "1" for one menu. There may be more than one
submenu and submenu names start with letters, which are
closer to the home row.
