This is very small plugin.
not sure I want to publish it in Addons Manager.
plugin works in WikidPad documents (it needs WikidPad lexer).
by double-click over CamelCaseWord in document, plugin looks for file CamelCaseWord.wiki
in the current folder, and opens it, or suggests to create it.
to install it:
call menu item "Plugins / Addons Manager / Install from Github", enter URL
