I just discovered the Super-W keystroke to show all the open applications, but I find the actual keystroke inconvenient and would love to remap it (say to one of the custom keys on my Microsoft 4000 keyboard).

You should be able to remap it with CCSM. See this answer for how to install CCSM. Then look under the Scale module of the Window management section. The key command is set in the Bindings tab.
You can set a new hotkey by replacing Super+W with whatever key combination you want, e.g. <Primary><Shift><Super>f
would be Ctrl+Shift+Super+F programmatically via the command line:
dconf write /org/compiz/profiles/unity/plugins/scale/initiate-key "'<Primary><Shift><Super>f'"
Another key combination of interest is the one to open all applications in all workspaces:
dconf write /org/compiz/profiles/unity/plugins/scale/initiate-all-key "'<Super>a'"

Leo, could you flesh out this answer a bit? How to actually change it from [super][W] would be a nice start... Otherwise the system will unfortunately delete your answer automatically because of low quality...– FabbySep 26, 2015 at 1:18
