#   Ctrl-T: Paste the selected files and directories onto the command-line
#   Ctrl-R: Paste the selected command from history onto the command-line
#   Alt-C:  cd into the selected directory
#
# The external .fzfrc file contains detailed color schemes, preview settings,
# and custom bindings for a clean, minimal interface with vim integration.
