@cascadeoftears ,
Actually, F7 switches to katakana and F6 to hiragana.
But only for the fresh input with mozc.
If you want a real toggle ie. with one key, I wish you good luck.
I’ve played with ydotool but the toggle feature did not worked for me.
cat ./moz_t.sh
#!/bin/sh
TOGGLE="$HOME/.toggle"
if [ ! -e $TOGGLE ]; then
ydotool key 64:1 64:0
touch $TOGGLE
else
ydotool key 65:1 65:0
rm $TOGGLE
fi
