As for what specific hexadecimal numbers represent in terms of functions, I found the answer on MSDN.

The following is an excerpt:
VK_BROWSER_BACK (0xA6)
Windows 2000/XP: Browser Back key
VK_BROWSER_FORWARD (0xA7)
Windows 2000/XP: Browser Forward key
VK_BROWSER_REFRESH (0xA8)
Windows 2000/XP: Browser Refresh key
VK_BROWSER_STOP (0xA9)
Windows 2000/XP: Browser Stop key
VK_BROWSER_SEARCH (0xAA)
Windows 2000/XP: Browser Search key
VK_BROWSER_FAVORITES (0xAB)
Windows 2000/XP: Browser Favorites key
VK_BROWSER_HOME (0xAC)
Windows 2000/XP: Browser Start and Home key
VK_VOLUME_MUTE (0xAD)
Windows 2000/XP: Volume Mute key
VK_VOLUME_DOWN (0xAE)
Windows 2000/XP: Volume Down key
VK_VOLUME_UP (0xAF)
Windows 2000/XP: Volume Up key
VK_MEDIA_NEXT_TRACK (0xB0)
Windows 2000/XP: Next Track key
VK_MEDIA_PREV_TRACK (0xB1)
Windows 2000/XP: Previous Track key
VK_MEDIA_STOP (0xB2)
Windows 2000/XP: Stop Media key
VK_MEDIA_PLAY_PAUSE (0xB3)
Windows 2000/XP: Play/Pause Media key
VK_LAUNCH_MAIL (0xB4)
Windows 2000/XP: Start Mail key
VK_LAUNCH_MEDIA_SELECT (0xB5)
Windows 2000/XP: Select Media key
VK_LAUNCH_APP1 (0xB6)
Windows 2000/XP: Start Application 1 key
VK_LAUNCH_APP2 (0xB7)
Windows 2000/XP: Start Application 2 key
B6 Application 1 is My Computer
B7 Application 2 is Calculator
In order to implement these functions more conveniently, I compiled a simple VBS
a=chr(&h88b5)
'msgbox "d" & a & "d"
CreateObject("wscript.shell").Sendkeys a
A simple explanation
a=chr(&h88b5)
' "&h" means the following number is a hexadecimal number, b5 represents Media key, that is, media player (such as千千静听). Why add 88 in front? After adding 88, there are two bytes, which form a Chinese character (in GBK). Because if the character represented by a is not a truly meaningful character (such as ASCII characters and Chinese characters), SendKeys will not work. You can try it. As for why 88 is chosen, because it is written in MSDN that (0x88-8F) Unassigned, and the characters starting with 88 can form meaningful GBK Chinese characters.
'msgbox "d" & a & "d"
' can test whether a is a meaningful character
CreateObject("wscript.shell").Sendkeys a
' call SendKeys method.
