I switch back and forth between a high-res, high-dpi monitor and my laptop, having the ability to hotkey the font size up and down would come in very handy, so I added it to teraterm.
Here's the diff. The change does "eat up" two user keys, but I didn't know about the ramifications of changing the NumOfUserKey macro.
ありがとうございます！
