When analyzing events, I often need to find similar events and do a "lateral" search. To do this, I have to create a new query based on a field that these events have in common, eg. EventGroupID, InitIP, or InitUserName. Adding another criteria to the existing query will not help in this case.
To facilitate this use case, I suggest that a new search tab is opened if a user CTRL-left clicks on a field. The criteria then should be the field the user clicked on.
And please make the values in the "show all fields" dialog click-able too.
