Looking for custom button documentations

Hello there,

I'm trying to learn custom button, I wanna start with the basic like understanding the parameters and what those fp0=1, lg4=1, lg1="TextCharacter" are for and how to use them. Can anyone suggest a documentation to help me start with these? I could not find useful information from Help and Training and I usually find answers here.

Mainly, I've been asked to have a custom button on a record page that will send an email and do a field update. 

Thanks a lot :)

The parameters are entirely dependent on the target of the custom button.  The examples that you have given would be processed by the target page of the button but without knowing what that is and how it works, we're unlikely to be able to help you.

If the target of the button is a standard page, its likely that you are referring to URL hacking, which is detailed in Ray Dehler's excellent blog post at:
