I have used Windows for all of my life. In Windows, shortcuts are (almost) always initiated with the Control key. Modifications to those shortcuts are then done with the ⇧ key. So, for example, you move to the next tab using ControlTab ↹ and move to the previous tab using Control⇧Tab ↹.
I have recently moved to OS X and I'm having a hard time remembering when to use ⌥ and when to use ⇧ in combination with ⌘. I almost never get it right. It is like it is random, but I want to think there is actually a rule.
So, does this rule actually exist?

Well, coming from a Windows background myself, I can state the following:
Between different Mac applications, there is sorta an effort to have some consistency in what certain key combinations do. For example, Ctrl+Cmd+f is usually a full-screen toggle.
However, the consistency of such keyboard shortcuts can vary per the software publisher.
Now, as a person that is familiar with Windows, you'll notice that Alt doesn't activate a menu mode, such as being able to drill down to a specific menu item.
However,you can create a keyboard shortcut via System Preferences >> Keyboard >> Shortcuts >> App Shortcuts. Just type the shortcut name as it appears in the application's menu.
