Special button description:
This keyboard is used in the same way as a normal PC keyboard. The
FN function key can be used in combination with the F1-F12 key.
Only htp:// http:// , ftp. www. , @ , .com The four buttons are
used when they are online, so they need to be used in English.
The specific use method is as follows: switch the input method to
the English state EN, press htp:// http:// , ftp. www. , @ , .com
to get the corresponding key value. After use, it can be washed
with water, disinfectant, alcohol or other cleaning solution.
