So, you did a search at some of the search engines and found some explanations for the computer jargon "middle click". Here is a point: Before doing such search, can't be sure will find a good answer. That was my point: There was no way for me to know before doing such a search that such a search would be successful. That is, the search engines are not guaranteed glossaries for all technical jargon in all technical fields. So, my explanation that I didn't know where to find a description of "middle click" was correct -- before trying a search at some search engines quite literally we did not "know" where we would find an explanation. Now that such a search has been successful, sure, we do know, but that fact is a bit weak as justification for using undefined jargon. So, since the search engines are not comprehensive glossaries for all technical jargon in all technical fields, given some technical jargon, a user has to make in effect shots in the dark, has to make these shots dark just to read a description of some product. I suggest that product developers should avoid asking their audience to make such shots in the dark just to read their product descriptions.
