Context menu got empty separator

I've just installed and then uninstalled iconStiX again - just to see where the stuff was placed.

The uninstall is like this (see Readme.pdf in iconStiX.dmg):

Throw away the following 4 items into the Trash:

• the iconStiX program in your Applications folder (or any other place of your choice)

• in your ~/Library/Preferences:

  • li.loos.trollin.iconStiX.plist

  • li.loos.trollin.iconStiX.LSSharedFileList.plist (if any)

• a folder named iconStiX in your ~/Library/Application Support folder

Empty the Trash.

BUT this doesn't remove the Contextual Menu Items - unless you reboot your Mac (I did that, and the items was gone).

I always have the same question but I didn't find the answer yet.

In Windows, when we use the keyboard short-cuts we mostly use the Menu key in Windows keyboard:

When this Menu key is pressed, Windows will assume that you right-clicked the highlighted/active element > then it will show you the context menu even if the mouse pointer is not pointing to the highlighted element.

So this feature seems to be missing in Mac OS. And whatever suggested solutions, even Enable Mouse Key it always require you to point/move your mouse pointer to element first, which is meaningless. If I need to use the keyboard short-cut to open the context menu on the highlighted item, why do I need again to move the mouse pointer to it also. Somehow this is not a short-cut!!
