# Script to show a list of keywords to automatically type for you when clicked.
# Assign this script to any spare key you have to trigger the selection popup,
# or assign to a macro keyboard key.
#
# Dependencies: yad, xdotool, wmctrl, pkill, printf.
# Note: Only tested on Linux Mint with XFCE desktop.

# The choices to show, 3 values per row (if less, an empty button is shown).
# You can use dynamic shell expansion, like $(date), and placeholder {SPACE} will be replaced by a real space.
#
# Example for TOTP codes, using https://github.com/susam/mintotp
# pip3 install mintotp
# Syntax: "Label###Value" where Value can be for example: $( mintotp <<< ZYTYYE5FOAGW5ML7LRWUL4WTZLNJAMZS )
# Make sure that Label does not contain normal spaces, use the {SPACE} when a space is needed.
