Windows Phrase pasting program + hot keys + mouse recoding

I need a self standing Windows ( that will work on every Windows version at least after 2000) application will paste the text from certain *.txt file whenever needed. Main function is to recode the behavior of the mouse as when user clicks right mouse button the original right-click menu will show also a new submenu (Phrases) as one of the "link" options. When cursor moved on the (submenu) then it shows - (Folder Names)- and again (name of text files / new submenu). When user clicks one of the given options then the app will paste the text content from a specific text file. When text files are saved/deleted/added the menu and submenus will update itself. The app needs function that it will override and show the menu also when an other *.exe program is running where the right-click menu is already changed. It will also need possibility so that certain files can be hot keyed to paste text from certain file as when e.g. CTRL+F1 pressed on keyboard.. etc. The program functions in this sense : [login to view URL] I will clarify the case when questions will appear.
