 It's called Hungarian notation 
(https://en.wikipedia.org/wiki/Hungarian_notation). It's one of the obsolete 
obnoxious things LibreOffice inherited from OpenOffice that keeps going on 
because of inertia.

 'm' is member, 'r' is reference, 'p' is pointer, 'x' is UNO reference, 'a' is 
array (or string), 's' is string, 'e' is enum, 'n' is number, 'b' is bool. Or 
maybe not, since in a number of variables it's wrong.

 I personally consider 'm' to be the only one useful and the rest is garbage 
that gets in the way and can be ignored.
