A "CEAddressString" is a string formatted for use by Cheat Engine's internal symbol handler to interpret an address
These addresses do not start with a 0x in front but do support basic math. Example: "00400500+12"
Pointers are written between [ and ]. Example: [[game.exe+1234]+12]+8 for a pointer that is written as:
8 12 game.exe+1234
The address specifier can also be a global lua symbol, but then it can only be the lua symbol. You do that by starting the CEAddressString with a '$'-sign. Example: $MyGlobalsymbol
