Currently Ctrl + clicking a node works to open it in a new tab, but you are true, that Ctrl does not take effect when performing Find More From Same, in which case the workaround is to click the (+) button to add another tab at fisr and then perfom the action on the new duplicated tab.

Organizing the library, it can be very useful to leave on Tab open and show the results of a search (via "Find more from the same") in a second Tab.
In Web Browsers "open links in a new tab" can be set.
That may be an easy way to go back to the selection in the first Tab and care for the next track.
May be an alternative option to realize sth. like [url=https://www.mediamonkey.com/forum/viewtopic.php?t=98429] "Pin Tab"[/url]
