#  Basic structure derived from the note taking application named zetz;
#    - https://gist.github.com/kutacoder/de2c0e624477efce920904125f0fb7b0
#
#  Prerequisites:
#    - tmux, fzf, bat, rg
#
#  Note File Format
#    - Notes should have a .md extention.
#    - Notes are created with a date-time formatted filename, set to the creation date in the follwing format: %Y%m%d%H%M%S
#    - Notes should have a title on the *first* line prefixed by one hash symbol. (title example: "# Cool Title")
#    - Notes should have one or more tags, starting on line 3. The tags should be prefixed by a hash
#      symbol without a space between it and the tag. Tags should also not have spaces in them. Use a
#      dash or underscore instead. (tag example: "#Cool-Tag")
#
#  Key Bindings:
#    - ctrl-r: reload list
#    - ctrl-x: delete note
#    - ctrl-i: add new note
