What I seek is a shortcut key combination instead of right clicking a file and choosing 'Create shortcut' in Windows 10.
Is there a shortcut key combination to 'Create shortcut'?
Select the file you wish to use to make the shortcut.
In my case I have to press s twice, then enter. because of another entry in the menu with the same shortcut.
s may need to be replaced by another letter on non-English versions of Windows.
You could program the required keystrokes into a macro program, such as Auto-It, AutoHotkey, or even the keyboard itself (if you have a programmable keyboard) in order to make a "shorter" shortcut key combination.
