Display filter field variables

[João Valverde via Wireshark-dev <wireshark-dev () wireshark org>]

Hi,

The GUI display filter has an interesting but little-known (?) feature 
to replace field values for the selected frame with the syntax 
${<field>}, which I only learned about in bug #15504, and confused me at 
first. This all happens before the expression is compiled and is 
different from display filter macros.

Does anyone know more about this? And where it is implemented in the GUI 
code?
