In Einstein's case, this was often necessary, because Einstein used very strange naming conventions.

A very simple example would be the symbols for the four used coordinate systems: K, k, K' and k'.

 These symbols are easy to remember: all are variants of K, which is
the first letter of Koordinaten-system. The only difference is that
K denotes the coordinate system K, k denotes the coordinate system k,
K' denotes the coordinate syste K', and k' denotes the coordinate
system k'. All coordinate systems are intertial, and much else is
not said about them so needn'd be remembered.
 

Well, but no.
The symbols K, k, K' and k' use two variations:
a) small and large letters
b) primed and not primed letters
Now 'small' means 'moving' (of k along the x-axis of K)
But 'primed' means what????
' was used to denote movement in subsequent chapters.
But here k' means the reverted movement of k along the x-axis of K with velocity -v.
To me these naming conventions were just terrible.
