# HyprKVM Move Handler
#
# This script intercepts workspace movement keybindings and routes them
# through HyprKVM to enable cross-machine navigation.

# Usage: hyprkvm-move.sh <direction>
# Directions: left, right, up, down
#
# Install in hyprland.conf:
#   bind = SUPER, Left,  exec, ~/.config/hypr/scripts/hyprkvm-move.sh left
#   bind = SUPER, Right, exec, ~/.config/hypr/scripts/hyprkvm-move.sh right
#   bind = SUPER, Up,    exec, ~/.config/hypr/scripts/hyprkvm-move.sh up
#   bind = SUPER, Down,  exec, ~/.config/hypr/scripts/hyprkvm-move.sh down
