Which registry key controls the right click options for selected text

In almost any file that contains text such as notepad, or any windows 'box' where typing is allowed, when you select some or all of the text displayed by highlighting it, the right click menu offered for the selected text contains things like 'Open IME' or 'Right to left Reading Order' and a few others including cut, copy, paste, and delete.
Is it possible to add any custom actions to the these and if so where would I do it?
If I wanted to use the selected text in an application, is there a way to use the selection as a variable passed to the application by adding an option for that function to this menu?

Thanks. I will see if that program works with Windows 10. I certainly don't mind buying a tool that will get the job done. The problem right now is I cannot even do it manually because I cannot find the right key to edit. The lines displayed for selected text always show those same options but when iI search the registry for "Open IME" or 'Right to left Reading Order' it always times out and never returns a key with those values.

Yeah, i see what you mean. I have just run through every tool in the toolbox. I cannot find anything that points directly to the specific location and action and there may not even be one. In the search, i did find a nifty tool named Textify "http://rammichael.com/textify" by an author I happen to know of but even that isn't a direct path to the action i am trying to accomplish. But getting closer
There are 100's of extensions to do this IF you are already in Chrome but getting a browser to open and use selected text is probably going to take some fancy scripting

Yes, such as in an email etc. I had seen that but i figured best to look for the most basic of entries and work my way up. I am now trying to write this into a vbs script and hopefully i can find a place to link that to the clipboard. Still not sure how to control the activation though.
I can get VBS to open my browser , open google Search. But that was the easy part. The text is loaded into the clipboard .. now if I can get something to inject the contents of clipboard into the google Search box which is where the focus is when the vbs runs I may get there yet,
Every site i searched from page 1 to page 15 in various google searches invariably leads back to already being in Chrome.

Thanks ARACHNAUT.!
I have been a fan of Nir Sofer since i saw his first package back in the days of Bulletin board postings. Back then I used to put the nircmd on every system I built. But I admit that I have not looked at it for along time. Though i have used many of his standalone utilities.

The only thing left to making this a perfect solution is my original search for a way to add ANY command to the right click options for selected text. Clipbrd.exe is no longer an "available" command in Win 10. While there are many replacements, most of them tried to one-up each other so i cant be sure that it only does the bare minimum needed.
If i can find a way to put the exact nircmd string for loading the registry location i have selected to clipboard that would be perfect. I may have to settle for copy to clip then click a hotkey to activate nircmd though

A short time back i asked a group of coders why someone hasn't written the app to scan all displayed text for any reference to a registry key and add a property to the text so it would work like a hyperlink. If clicked it would open regedit to that key if it exists or to the nearest matching location if not. I can already scan a full screen of data and have the text "READ" to me by a "bot" so obviously recognizing text is not the problem.

In my case, i would want the 'bot' to highlight the keys much as hyperlinks are highlighted and add the "jump to key in regedit" feature to any that are clicked like hyperlinks jump to websites.

Since no one has, that is what I am trying to do. A poor-man's simple version of the same capability done one by one as needed.
