What a “mixed up, muddled up, shook up” puzzle, except for 18A. I had a problem in the SW corner, with ISA_ crossing _ EN. “Oho!” Is another filler word that could mean anything. ISAY, ISAW, whatever. And everyone knows “WEN” is a form of copper currency used in Imperial China. It took several passes trying to find my mistake before I realized modern Japanese currency also fit, allowing me to pour a glass of champagne to celebrate. Of course it tasted just like C-O-L-A Cola

Solving on my phone I couldn’t just scan for the italicized entries and didn’t notice the crossing rebus downs were also in italics. When I got to the revealer after already having solved the three rebus acrosses and had only the SE left I was wondering how he was going to fit three more ANSWERKEYS (DEL, INS and CTRL?) in that corner.
