Sogou input method can't stop. What happened? Every time you press the period, the key will display the switching between Chinese and English symbols, but the period cannot be played. What should I do? Urgent! This can be solved by setting the Chinese-English switch key. I can't remember the details. The system language bar should have a small triangle. Click on the selection options and shortcut key settings, and set the Chinese-English switch key to something else (such as shift). Sogou input method seems to have this function. You can look for it.
