# This will open a fzf menu over the `~/cheatsheets` directory.
# You can select one of the files there, or use the special command `new` which
# creates a new file (you will be prompted for a title, which should not include
# the .md extension).
# NOTE: Currently hardcodes cheatsheets directory to `~/cheatsheets`.
