###############################################################################

# Description:

#

# Copy2Clipboard will automatically copy a single card field to the clipboard

# when either the card's question side is shown or when the card's answer side

# is shown (or both, if desired).

#

# Default behavior:

#

#   * When the card's question is shown:

#       Nothing will be copied to the clipboard.

#

#   * When the card's answer is shown:

#       The card's "Expression" field will be copied to the clipboard (if one exists).

#

# To change the default behavior simply edit the questionField or answerField

# variables in the User Options section of this file.

#
