There is one global keyboard shortcut that is available everywhere, and that can be changed from the preferences window. You can change this shortcut to be something that doesn't conflict with any of your existing shortcuts. The other shortcuts only work once you've pressed the global shortcut. So for example, if your global shortcut is (the default) ⌘E, to open the task list you would press ⌘E and while still holding down command press F.
