--Pinboard tools for ELinks
--source from your ~/.elinks/hooks.lua file with `dofile("pinboard.lua")`

--CTRL+p to save a bookmark. Brings up an XDialog, first row is to enter a description, second row is for tags
--CTRL+o to read later (It's next to p. You try and find a none conflicting keyboard shortcut in Elinks)
--Reformats the mobile site to be better for ELinks

--In order to be able to delete need to enter auth_token in `.netrc`. See README
