Keyboard Short Cuts (doesnt' accept custom keys)

[Anonymous]

I changed  "mirror draw axis" from MI to SD.

(I deleted any short cuts assigned for "SD", no duplicates, no double shorts cuts for single command)

The new key "SD" doesn't work. But, if I changed back to the original "MI," then it works. 

There are a lot of keys like this. I think it is some sort of the program bug

I recently had this issue.
Basically you can use 3 letter shortcuts but by doing this you cannot have other shortcuts using the first 2 letters of the 3 letter shortcut.

Otherwise when you have this the situation described above, Revit keeps waiting for a possible third letter.
