The list is a bit old, but maybe it helps with some odd keys. Now that unicode is pretty common, I try to stick to the ellipsis for example… I have to say that the compose position for dieresis is a bit more logical (compose-" as opposed to macs alt-u), which is quite useful if I don't want to switch keyboard layouts when typing a bit of German (or write a lot about Motörhead and Queensrÿche).
X11 also has "level 3" support, which is straight-forward additional characters when pressing a certain key, as opposed to combining multiple key presses. Mac's alt key basically does both to a certain degree. The fact that it's turned on by default and the keyboard viewer makes it a lot more common usage in my experience.
