Things I have tried

我莫名其妙按了"Ctrl ="好几次，然后obsidian的界面UI的字体就变的很大很大，我也没发现其他按键可以撤销这个。现在就是用不了了，难受的很。
I just pressed “Ctrl =” more times, and it‘s even worse. I’m very regret about that. I don’t
how to undone “Ctrl =”.
Please HELP me !

What I’m trying to do

Please try typing Ctrl-0 (zero) to reset the font size.

Also, Ctrl-minus should reduce the font size.
