I've recently discovered the pager "most". most can make the manpages colorful and I like it. I want to change some of its bound keys and from the manpage of most I found out it's possible to do that. But I don't think the manpage (link) has described precisely. In the CONFIGURATION FILE SYNTAX section of the manpage, function-name is mentioned but how do I know all the function names?
Here is a picture of the manpage of most
I raised this question in stackoverflow first and was told that it's a better choice to post the question here. Any help will be appreciated!.
Update: OS:ubuntu 16.04
the way I install most: apt-get

most? What Unix/Linux are you using? at least in Debian based systems, themostpackage appears to place some example configuration files in/usr/share/doc/most/- in particular, the file/usr/share/doc/most/most-fun.txtlists the functions that may be used in custom keymaps
