vim suddenly cannot input in ubuntu

Problem description: In vim, I suddenly found that I can’t input by pressing the keyboard (only in vim, I can’t input)

Reason: I pressed ctrl+s by mistake to lock the scroll. I actually entered it but could not see the effect;

Solution: ctrl+q cancels the scroll lock;

Note: If you want to disable the locked scrolling function, open the configuration file ~/.bashrc and add stty -ixon, then reload the configuration file source ~/.bashrc;
