 DD Mmm 20 - 1.53
 
+add: /searchconsole begins a new console search
+  press ctrl-F when the console is down to bring up the command
+  press (shift-)F3 to find the next match going up or down
+  just like in cmdlist/cvarlist/etc, * will match any amount of characters
+
 add: r_ignoreShaderSortKey <0|1> (default: 0) ignores the shader sort key of transparent surfaces
   instead, it sorts by depth and original registration order only
   this is a work-around for broken maps like bones_fkd_b4 (grates drawn in front of simple items)
