## 9.8. Display Filter Macros

Display Filter Macros are a mechanism to create shortcuts for complex filters. For example defining a display filter macro named tcp_conv whose text is ( (ip.src == $1 and ip.dst == $2 and tcp.srcport == $3 and tcp.dstport == $4) or (ip.src == $2 and ip.dst == $1 and tcp.srcport == $4 and tcp.dstport == $3) ) would allow to use a display filter like ${tcp_conv:10.1.1.2;10.1.1.3;1200;1400} instead of typing the whole filter.

Display Filter Macros can be managed with a Section 9.7, “User Table” by selecting the Display Filter Macros menu item from the View Menu. The User Table has the following fields

name

  The name of the macro.

text

  The replacement text for the macro it uses $1, $2, $3, ... as the input arguments.
