+####################
+
+# The key with the house icon (between Fn and left Alt) IS Super_L.
+# On uConsole: that bottom-row key left of spacebar = SUPER.
+# If it doesn't work, use ALT instead:
+# $mainMod = ALT   (affects ALL binds below)
+#
+# Additional ALT bindings for convenience (work alongside SUPER):
+# Note: SUPER+KEY and ALT+KEY both trigger the same action
