[links] personalizing keybindings

[Nath]

Hello,

Can someone help me to write a ~/.links/user.cfg file in order to
personalize links keybindings. I search for the proper solution since
this morning but unfortunatly don't find anything very helpfull on the
web. 
For example I entered the line 
bind main F1 toggle-html-plain
but it doesn't work at all !

so if someone has ever write a such file to define his/her personal
keybindings in links please let me know how you proceed exactly, what is
the proper syntax.
Thx in advance,
