"why did you revert to X1d from X2?"
Because X1d Expanded and Win 7x64 are a "mature and robust" audio production environment.
Not trying to be contentious here, I'm using X2a, but ONLY for personal non-critical stuff.

The "*" indicates you have modified a keyboard shortcut.
F11 does not insert a marker on my system, M does (as noted by g_randy above).
I've extensively modified my Key Shortcuts, there's an import/export dialog in the Prefs.
