This quick sketch was done to test a few techniques. Vision
was to have
1) vi as a sort of form-editor to select/assemble parameters for something
2) expect to get through ssh boundaries and be able to init remote apps
3) navigate the prefix menu with keystrokes (quick)
Prefix menu works like giving a list of files, all files should have
a unique starting character, keypress is read, then
. was pressed, it results a cd .. (in case you're already at the root, the menu session ends)
entered character is the first character of a
- file, it's executed, like ./file
- directory, session continues/repeats in that directory
