# Use keyboard shortcuts to copy the selection to the clipboard and to paste
# the clipboard contents (optionally escaping all special characters).
# Requires xsel to be installed!

# Usage: put the following lines in your .Xdefaults:
#   URxvt.perl-ext-common: ...,clipboard
#   URxvt.keysym.M-c:   perl:clipboard:copy
#   URxvt.keysym.M-v:   perl:clipboard:paste
#   URxvt.keysym.M-C-v: perl:clipboard:paste_escaped

# The use of the functions should be self-explanatory!
